This application is based on Japanese Patent Application No. 2022-177138 filed on Nov. 4, 2022, the contents of which are incorporated herein by way of reference.
The present invention relates to a holder for a long member that holds the long member with a line shape, a tubular shape, or a rod shape.
For example, pipes, tubes, wires, cables, harnesses, and the like are used in automobiles, but are entangled, interfere with other members, or are damaged in some cases. Therefore, such things are usually housed and held in some holders and are often arranged at predetermined positions inside vehicles via the holders.
For example, the following Patent Literature 1 discloses a holder that is fixed to a fixed member including a shaft member via the shaft member and holds a long member.
The holder for the long member includes a holding member that includes a frame-shaped body portion to which a holding portion for holding the long member is connected, an anti-vibration member that is made of an elastic material and includes a frame-shaped portion inserted into the frame-shaped body portion, and a fixing member that includes an insertion portion inserted into the frame-shaped portion and receives the shaft member, and that provided with a locking portion locked to the shaft member inside the insertion portion.
A first engagement portion is provided inside the frame-shaped body portion and a second engagement portion engaging with the first engagement portion is provided on an outer surface of the insertion portion. Further, a third engagement portion is provided inside the frame-shaped body portion and a fourth engagement portion engaging with the third engagement portion is provided on an outer surface of the frame-shaped portion. A push-in portion is provided on the base end side of the fixing member and an outer circumference of the push-in portion has a shape overhanging in a flange shape.
When each member of the holder is assembled, the frame-shaped portion is inserted into the frame-shaped body portion and the third engagement portion engages with the fourth engagement portion to attach the anti-vibration member to the holding member. Thereafter, the insertion portion is inserted into the frame-shaped portion and the first engagement portion engages with the second engagement portion to attach the fixing member to the holding member, so that the holder is assembled. When the holder is assembled, a flange of the fixing member faces an upper end surface of the frame-shaped body portion.
Incidentally, when the long member is held by the holder as in Patent Literature 1 as described above, the long member is generally held to be substantially parallel or at a predetermined angle with respect to a fixed surface of the fixed member.
However, when a force that twists the long member, that is, a force that causes the long member to approach or move away from the fixed surface of the fixed member is applied, the flange of the fixing member and the upper end surface of the frame-shaped body portion may come into contact with each other and interfere with each other in some cases. Then, for example, vibration or the like occurring from the long member may be transmitted to the fixing member via the frame-shaped body portion, and thus anti-vibration performance of the anti-vibration member cannot be sufficiently achieved because the anti-vibration member is not involved.
Accordingly, an object of the present invention is to provide a holder for a long member that hinders the holding member and the fixing member from interfering with each other to sufficiently achieve anti-vibration performance of the anti-vibration member even when a force that twists the fixing member is applied.
A holder for a long member is configured to be fixed to a fixed member including a shaft member via the shaft member and is configured to hold the long member. The holder includes: a holding member that includes a frame-shaped body portion to which a holding portion for holding the long member is connected:, an anti-vibration member that is made of an elastic material and includes a frame-shaped portion configured to be inserted into the frame-shaped body portion; and a fixing member that is provided with an insertion portion configured to be inserted into the frame-shaped portion and configured to receive the shaft member, and a locking portion configured to be locked to the shaft member inside the insertion portion. The insertion portion includes an extension portion extending in an insertion direction in which the insertion portion is inserted into the frame-shaped portion. A pressing protrusion protrudes on an outer surface of the extension portion, and when the frame-shaped portion is inserted into the frame-shaped body portion and the insertion portion is inserted into the frame-shaped portion, the pressing protrusion presses an inner surface of the frame-shaped portion and an outer surface of the frame-shaped portion comes into pressing contact with an inner surface of the frame-shaped body portion.
Hereinafter, a first embodiment of a holder for a long member according to the present invention will be described with reference to

Next, each member included in the holder 10 will be described.
First, the holding member 20 will be described with reference to
The frame-shaped body portion 30 in the embodiment includes a pair of walls 31, 31 that face each other in parallel and a pair of walls 33, 33 which are orthogonal to the pair of walls 31, 31 and face each other, and has a substantially quadrangular frame shape in which one end 35 side and the other end 36 side are opened.
The one end 35 side of the frame-shaped body portion 30 is a side away from the fixed member 1 and the other end 36 side of the frame-shaped body portion 30 is a side opposite to the one end 35 side and close to the fixed member 1 (a side facing the fixed surface 3 of the fixed member 1). The same also applies to “one end side” or “the other end side” in each portion (the frame-shaped portion 51 or the like) of the anti-vibration member 50 or each portion (the insertion portion 81 or the like) of the fixing member 80 to be described below, or the foregoing shaft member 5.
The frame-shaped portion 51 is inserted from an opening on the other end 36 side of the frame-shaped body portion 30.
A pair of recessed portions 37 that has a recessed groove shape at a predetermined depth from the outer surface are formed on both sides in the width direction (a direction orthogonal to an arrangement direction of the pair of walls 33, 33) and on a side of the outer surface of each wall 33 (a surface opposite to the inner surface of the frame-shaped body portion 30 oriented inward) (see
Further, as illustrated in
In each first engagement portion 43, a fixing end is connected to the one end 35 side of the frame-shaped body portion 30 and a free end is disposed on the other end 36 side of the frame-shaped body portion 30. The free end protrudes on the inner side of the frame-shaped body portion 30. The first engagement portion 43 faces the fifth engagement portion 91 provided in the fixing member 80 and can engage with the fifth engagement portion 91 (see
As illustrated in
The second engagement portion 45 can engage with the third engagement portion 69 provided in the anti-vibration member 50 (see
On the other hand, the holding portion 21 is consecutively connected to one wall 31 side of the pair of walls 31, 31 included in the frame-shaped body portion 30.
As illustrated in
As illustrated in
Next, the anti-vibration member 50 will be described with reference to
As illustrated in
Referring together to
The frame-shaped portion 51 with a substantially quadrangular frame shape has a shape similar to and smaller than the frame-shaped body portion 30 with a substantially quadrangular frame shape.
Specifically, a width (a length in a direction orthogonal to an arrangement direction of the pair of walls 53, 53) of each wall 53 of the frame-shaped portion 51 is smaller than a width (a length in a direction orthogonal to an arrangement direction of the pair of walls 31, 31) of each wall 31 of the frame-shaped body portion 30. Further, the width (the length in the direction orthogonal to the arrangement direction of the pair of walls 53, 53) of each wall 53 of the frame-shaped portion 51 is smaller than a width (a length in the direction orthogonal to the arrangement direction of the pair of walls 33, 33) of each wall 33 of the frame-shaped body portion 30.
As a result, the frame-shaped portion 51 can be inserted into the frame-shaped body portion 30. In the insertion state, there is a predetermined gap between an entire inner circumference of the frame-shaped body portion 30 and an entire outer circumference of the frame-shaped portion 51.
A length (a length in the frame-shaped portion insertion direction F1) of the pair of walls 55, 55 included in the frame-shaped portion 51 is shorter than a length of the pair of walls 53, 53 in which the extension pieces 60 are provided. Here, as illustrated in
Further, in the frame-shaped portion 51, a contact portion 57 that protrudes further than the other end 36 of the frame-shaped body portion 30 and comes into contact with the fixed member 1 is provided on the other end 51b side. The contact portion 57 includes a flange 58 with a thin plate shape that is overhung outwards from the outer circumference of the frame-shaped portion 51 on the other end 51b side and a pedestal 59 that protrudes from the surface of the flange 58 on the other end 51b side.
As indicated by the frame-shaped portion insertion direction F1 in
The anti-vibration member 50 includes the extension pieces 60 that extend to protrude from the frame-shaped body portion 30 (see
As the extension pieces 60 will be described more specifically, each of the extension pieces 60, 60 extends from one end of each of the pair of walls 53, 53 included in the frame-shaped portion 51 (ends of the frame-shaped portion 51 on the one end 51a side).
Each extension piece 60 extends integrally and continuously from one end of the wall 53 to the wall 53 and extends straight to the wall 53 before the frame-shaped portion 51 is inserted into the frame-shaped body portion 30. Further, the extension piece 60 extends long further than the end of the wall 55 on the one end 51a side before the frame-shaped portion 51 is inserted into the frame-shaped body portion 30.
As illustrated in
The distal end 61 of each extension piece 60 is pressed by the flange 95 of the fixing member 80 or a part (the pressing surface 101) of the insertion portion 81, so that the pair of extension pieces 60, 60 are curved and deformed outwards and the distal ends 61, 61 are separated from each other with a base end (also referred to as the other end and indicating a connection portion or a boundary portion with the one end of the wall 53) of each extension piece 60 as a starting point (see
In the state where the pair of extension pieces 60 are pressed apart, as illustrated in

As illustrated in
On the outer surface of the wall 53, first protrusion ridges 65 which are protrusion ridges extending in the extension direction and coming into contact with the inner surface of the frame-shaped body portion 30 are formed with a length which does not reach the distal end 61 (one end) of the extension piece 60.
In the embodiment, in the intermediate portion of the outer surface (a surface opposite to the inner surface of the frame-shaped portion 51 oriented inward) of each wall 53 in the width direction, the pair of first protrusion ridges 65 extend in parallel to each other in the extension direction of the wall 53. Each first protrusion ridge 65 extends by a length in which the other end is connected to the flange 58 included in the contact portion 57 and one end does not reach the base end of the extension piece 60.
When the frame-shaped portion 51 is inserted into the frame-shaped body portion 30, as illustrated in
Within a predetermined range which reaches the base end (the other end) side from the distal end (one end) of each wall 55 in the extension direction, a pair of slits 66, 66 extending in parallel to each other are formed, and each of bendable and deformable elastic pieces 67 is formed via the pair of slits 66, 66. As illustrated in
Further, the third engagement portion 69 protrudes at the distal end of each elastic piece 67 in the intermediate portion of the outer surface (the surface opposite to the inner surface) of the distal end in the width direction. As illustrated in

A location which is fitted at a position at which the third engagement portion 69 is provided on the inner surface of the elastic piece 67 (one member included in the frame-shaped portion 51) formed on the wall 55 of the frame-shaped portion 51, that is, a location which is fitted in the third engagement portion 69 in the axial direction of the frame-shaped body portion 30 or the frame-shaped portion 51 (the tapered surface 67a of the inner surface of the distant end of the elastic piece 67), is pressed by the pressing protrusion 103 (see
Further, as illustrated in
The slits 66 form the elastic pieces 67 and also have the following role. That is, as indicated by the frame-shaped portion insertion direction F1 in
In both edges in the width direction on the outer surface of the elastic piece 67, a pair of second protrusion ridges 71, 71 which are protrusion ridges extending in the insertion portion insertion direction F2 are provided. Each second protrusion ridge 71 extends on the outer surface of the wall 55 beyond a base end of the elastic piece 67 from one end of the elastic piece 67, and the other end thereof is connected to the flange 58 included in the contact portion 57. That is, it is also said that the second protrusion ridge 71 extends to the outer surface of the elastic piece 67 and the outer surface of the wall 55.
When the frame-shaped portion 51 is inserted into the frame-shaped body portion 30, as illustrated in
That is, as illustrated in
A recessed groove 73 with a recessed groove shape is formed at a portion between each second protrusion ridge 71 and the third engagement portion 69 adjacent thereto on the outer surface of the elastic piece 67. As illustrated in
More specifically, in the state where the frame-shaped portion 51 is inserted into the frame-shaped body portion 30, the recessed grooves 73 are separated from the inner surfaces of the pair of protrusions 39, 39 included in the walls 33 and are also separated from boundary portions (corners) of the protrusions 39 and the inner surfaces 39a (see
Further, as illustrated in
Next, the fixing member 80 will be described with reference to
The fixing member 80 includes the insertion portion 81 that is inserted into the frame-shaped portion 51 and receives the shaft member 5, the locking portions 94 that are provided inside the insertion portion 81 and are locked to the shaft member 5, and the flange 95 that is overhung on one end 81a side of the insertion portion 81.
The insertion portion 81 in the embodiment includes a pair of first extension portions 83, 83 that have a long plate shape extending by a predetermined length in the insertion direction in which the insertion portion 81 is inserted into the frame-shaped portion 51 (insertion portion insertion direction F2) and face each other in parallel, a distal end 85 that is connected to distal ends of the pair of first extension portions 83, 83 (the end of the insertion portion 81 on the other end 81b side), and a push-in portion 87 that is connected to the base ends of the pair of first extension portions 83, 83 (the end of the insertion portion 81 on the one end 81a side, has a substantially quadrangular plate shape, and is a portion that is pushed by a worker assembling the holder 10.
In the intermediate portions of the push-in portion 87 and the distal end portion 85, circular shaft holes 85a and 87a into which the shaft member 5 is inserted are formed, respectively (see
Further, the pair of second extension portions 88 and 89 extending in a columnar shape along the insertion portion insertion direction F2 are disposed at portions between the distal end 85 and the push-in portion 87 at positions which do not interfere with the shall member 5 inserted into the shaft holes 85a and 87a. The distal end 85 and the push-in portion 87 are connected to each other by the pair of second extension portions 88 and 89, and thus the entire fixing member 80 is reinforced.
As illustrated in
Further, as illustrated in
In the embodiment, the fifth engagement portions 91 protrude in a planar direction of each first extension portion 83 (a direction orthogonal to an arrangement direction of the pair of first extension portions 83, 83 and along the outer surface of the first extension portions 83) from predetermined positions of both side edges 84, 84 (see
The sixth engagement portions 93 are formed at positions closer to the fixed member 1 than the fifth engagement portions 91, specifically, positions close to the end (the distal end 85) in the insertion portion insertion direction F2, on both the side edges 84, 84 of each first extension portion 83.
In the insertion portion 81, four fifth engagement portions 91 and four sixth engagement portions 93 are provided. As illustrated in

The flange 95 is overhung from the outer circumference of the one end 81a of the push-in portion 87 included in the insertion portion 81.
As illustrated in
As illustrated in
On the other hand, as illustrated in
As illustrated in
The flange 95 is formed with a width narrower than the width of the extension piece 60 provided in the anti-vibration member 50. As a result, in a state where the frame-shaped portion 51 is inserted into the frame-shaped body portion 30, the insertion portion 81 is inserted into the frame-shaped portion 51, and the anti-vibration member 50 and the fixing member 80 are assembled in the holding member 20, the flange 95 is not overhung (does not protrude) from the outer circumferential edges of the pair of extension pieces 60, 60.
As illustrated in

When the frame-shaped portion 51 is inserted into the frame-shaped body portion 30 and the insertion portion 81 is inserted into the frame-shaped portion 51, the pressing surfaces 104 and the tapered surfaces 105 of the pair of pressing protrusions 103, 103 press the tapered surface 67a, 67a of the inner surfaces of the distal ends of the pair of elastic pieces 67, 67, as illustrated in
In the holding member, all the portions (the holding portion, the frame-shaped body portion, the first engagement portions, the second engagement portions, and the like) are integrally formed with a known synthetic resin material. The shape, the structure, the layout, and the like of each portion of the holding member are not particularly limited.
The holding portion 21 in the embodiment can retain and hold two long members P. However, for example, the holding portion may have a structure capable of retaining and holding one long member or three or more long members, Further, the frame-shaped body portion 30 in the embodiment includes four first engagement portions 43 and the pair of second engagement portions 45, 45, but the number of engagement portions is not particularly limited.
In the anti-vibration member, all the portions (the frame-shaped portion, the contact portions, the extension pieces, the elastic pieces, the first and second protrusion ridges, the third and fourth engagement portions, and the like) are integrally formed with an elastic resin material with anti-vibration performance, such as rubber or an elastic elastomer. Further, the shape, the structure, the layout, and the like of each portion of the anti-vibration member are not particularly limited.
In the embodiment, the pair of extension pieces 60, 60 are included, but two or more pairs of extension pieces may be included. The extension pieces 60 in the embodiment is pressed by the pressing surfaces 101 which are parts of the insertion portion 81 of the fixing member 80 to he bent and deformed, but the extension pieces may have a structure that is bent and deformed by being pressed by a flange of the fixing member.
Further, in the embodiment, the pair of third engagement portions 69 and the four fourth engagement portions 75 are included, but the number of engagement portions is not particularly limited. Two first protrusion ridges 65 and two second protrusion ridges 71 extend on the outer surfaces of the walls 53 and 55, but the first and second protrusion ridges may be provided alone, or may be three or more.
Further, in the fixing member, all the portions (the insertion portion, the fifth and sixth engagement portions, the locking portions, the flanges, and the like) are integrally formed with a known synthetic resin material. Further, the shape, the structure, the layout, and the like of each portion of the fixing member are not particularly limited.
Further, in the embodiment, the outer circumferential shape of the flange 95 is a substantially rectangular shape. However, the outer circumferential shape of the flange may he, for example, a square shape, a triangular shape, a polygonal shape more than a pentagonal shape, a circular shape, an oval shape, an elliptical shape, a rugby ball shape, or the like or may have a width narrower than the width of the extension piece.

In the embodiment, as illustrated in
Next, a method of using the holder 10 that has the foregoing configuration will be described.
First, the holder 10 including the holding member 20, the anti-vibration member 50, and the fixing member 80 is assembled.
That is, in a state where the third engagement portions 69 of the anti-vibration member 50 are positioned in a space between the pair of protrusions 39, 39 provided in the frame-shaped body portion 30, as indicated by the frame-shaped portion insertion direction F1 in
Then, the pair of first protrusion ridges 65, 65 come into sliding contact with the inner surfaces of the pair of walls 31, 31 of the frame-shaped body portion 30, the third engagement portions 69 are entered between the inner surfaces 39a, 39a of the pair of protrusions 39, 39 of the frame-shaped body portion 30, and the first engagement portions 43 are moved into the slits 66. Further, the outer surfaces of the third engagement portions 69 are pressed against the inner surfaces of the pair of walls 33, 33 of the frame-shaped body portion 30, and thus the pair of elastic pieces 67, 67 are inserted to be bent and deformed so that the distal ends are close to each other.
The frame-shaped portion 51 is pushed until the flange 58 of the contact portion 57 of the frame-shaped portion 51 comes into contact with the end surface of the frame-shaped body portion 30 on the other end 36 side. Then, the pair of extension pieces 60, 60 of the frame-shaped portion 51 protrude from the end surfaces of the frame-shaped body portion 30 on the one end 35 side (see
In addition, the third engagement portions 69 climb over the second engagement portions 45 of the frame-shaped body portion 30, and the bent and deformed elastic pieces 67 are elastically returned. As illustrated in
Thereafter, in the state where the pair of fifth engagement portions 91, 91 of the insertion portion 81 of the fixing member 80 are positioned in the pair of slits 66, 66 of the frame-shaped portion 51 inserted into the frame-shaped body portion 30, as indicated by the insertion portion insertion direction F2 in
Then, the pair of fifth engagement portions 91, 91 of the insertion portion 81 are moved into the pair of slits 66, 66 of the frame-shaped portion 51, the fifth engagement portions 91 press the first engagement portions 43 of the frame-shaped body portion 30, and the first engagement portions 43 are bent and deformed outwardly of the frame-shaped body portion 30.
Further, when the insertion portion 81 is pushed into the frame-shaped portion 51, the inner surfaces (here, the tapered surfaces 63, 63) of the distal ends 61, 61 of the pair of extension pieces 60, 60 are pressed by the pair of pressing surfaces 101, 101 provided in parts of the insertion portion 81 so that the pair of extension pieces 60, 60 are bent and deformed to be curved outwards.
The pushing-in is performed until the outer surfaces of the distal ends 61, 61 of the pair of extension pieces 60, 60 come into contact with the end surfaces of the pair of walls 31, 31 included in the frame-shaped body portion 30 on the one end 35 side, and the pair of first flanges 96, 96 included in the flanges 95 conic into contact with the inner surfaces of the distal ends 61, 61 of the pair of extension pieces 60, 60.
Then, the maximum insertion position of the insertion portion 81 to be inserted into the frame-shaped portion 51 is regulated, the fourth engagement portions 75 of the frame-shaped portion 51 are entered into the sixth engagement portions 93 of the insertion portion 81, and the sixth engagement portions 93 and the fourth engagement portions 75 engage with each other (see
In addition, each fifth engagement portion 91 climbs over each first engagement portion 43, and thus each first engagement portion 43 is elastically returned. As illustrated in

As described above, after the holder 10 is assembled, the holder 10 is fixed to the fixed member 1 via the shaft member 5. That is, the holder 10 is pushed toward the fixed member 1 in a direction close to the fixed surface 3.
Then, the shaft member 5 passes through an opening of the frame-shaped portion 51 on the other end 51b side from the other end side of the shaft member 5, is received inside the insertion portion 81, and is locked to the plurality of locking portions 94. Thereafter, by pushing the holder 10 until the pedestal 59 of the contact portion 57 of the frame-shaped portion 51 comes into contact with the fixed surface 3, the holder 10 can be fixed to the fixed member 1 via the shaft member 5.
Subsequently, by inserting the long member P into the holding space 27 of the holding portion 21, it is possible to hold the long member P by the holding claws 29 and arrange the long member P in the fixed member 1 via the holder 10 (see
In the holder 10, when the frame-shaped portion 51 is inserted into the frame-shaped body portion 30 and the insertion portion 81 is inserted into the frame-shaped portion 51, the pressing protrusions 103, 103 provided in the extension portions (the second extension portions 88 and 89) press the inner surfaces (the inner surfaces of the distal ends of the pair of elastic pieces 67, 67) of the frame-shaped portion 51, and the outer surfaces (the outer surfaces of the second protrusion ridges 71) of the frame-shaped portion 51 accordingly come into pressing contact with the inner surfaces (the inner surfaces of the protrusions 39, 39 of the pair of walls 33, 33) of the frame-shaped body portion 30 (see
Therefore, even when a force that twists the long member P held in the holding portion 21 (hereinafter simply referred to as a “twisting force”), that is, for example, as indicated by a two-dot chain line in
As a result, in the holder 10, a transmission path of vibration hardly occurs without involving the anti-vibration member 50 (it is possible to suppress the generation of a transmission path of vibration that occurs when the frame-shaped body portion 30 and the fixing member 80 come into contact with each other). Therefore, the anti-vibration member 50 can have sufficient anti-vibration performance.
In the embodiment, as illustrated in
According to the foregoing aspect, the pressing protrusions 103, 103 protrude from the outer surfaces of the portions of the pair of second extension portions 88 and 89 opposite to the insertion portion insertion direction F2. Therefore, from a time at which the insertion portion 81 is he inserted into the frame-shaped portion 51 to a time at which the flanges 95 approach or come into contact with the distal ends 61, 61 of the pair of extension pieces 60, 60, the pressing protrusions 103 do not press the inner surface of the frame-shaped portion 51. When the flanges 95 come into pressing contact with the distal ends 61, 61, the pressing protrusions 103 press the inner surfaces of the frame-shaped portion 51 for the first time.
As a result, since an insertion resistance when inserting the insertion portion 81 into the frame-shaped portion 51 can be reduced, the insertion portion 81 can be smoothly inserted into the frame-shaped portion 51.
Since the inner surface of the frame-shaped portion 51 on one end 51a side is pressed locally and strongly by the pressing protrusions 103, a pressing contact force of the outer surface of the frame-shaped portion 51 to the inner surface of the frame-shaped body portion 30 can be increased. As a result, it is possible to inhibit tilting or the like of the frame-shaped body portion 30 more efficiently when the twisting force is applied to the long member P.
Further, in the embodiment, the engaged portions (the second engagement portions 45) are provided on the inner surface of the frame-shaped body portion 30. Further, when the frame-shaped portion 51 is inserted into the frame-shaped body portion 30, the engagement portions (the third engagement portions 69) engaging with the engaged portions are provided on the outer surface of the frame-shaped portion 51. The pressing protrusions 103 press locations which are fitted at positions at which the third engagement portions 69 are provided on the inner surface of the frame-shaped portion 51 (see
According to the foregoing aspect, the pressing protrusions 103 press the locations which are fitted at the positions at which the third engagement portions 69 are provided on the inner surface of the frame-shaped portion 51. Therefore, at the engagement locations of the third engagement portions 69 and the second engagement portions 45, it is possible to improve a pressing contact strength on the outer surface of the frame-shaped portion 51 with respect to the inner surface of the frame-shaped body portion 30. Tilting or the like of the frame-shaped body portion 30 is inhibited while reliably maintaining an attachment state of the holding member 20 and the anti-vibration member 50, and anti-vibration performance of the anti-vibration member 50 can be sufficiently achieved.
The holding member 20 and the anti-vibration member 50 can have a shape structure which can be engaged efficiently and functionally. When the pressing protrusions press locations unrelated to the engagement between the engaged portions and the engagement portions, it is difficult to achieve a reliable attachment state. Therefore, there is a possibility of anti-vibration performance deteriorating.
In the embodiment, in the frame-shaped portion 51, the bendable and deformable elastic pieces 67 are formed via the pair of slits 66, 66, the engagement portions (the third engagement portions 69) are provided in the elastic pieces 67, and the inner surfaces of the elastic pieces 67 are pressed by the pressing protrusions 103.
When the frame-shaped portion 51 is inserted into the frame-shaped body portion 30, it is necessary for the third engagement portions 69 provided on the outer surface of the frame-shaped portion 51 to climb over the engaged portions (the second engagement portions 45) provided on the inner surface of the frame-shaped body portion 30. At this time, in the present embodiment, the third engagement portions 69 are formed in the bendable and deformable elastic pieces 67 via the pair of slits 66, 66. Therefore, the third engagement portions 69 can easily climb over the second engagement portions 45, and thus it is easy to insert the frame-shaped portion 51 into the frame-shaped body portion 30.
Since the pressing protrusions 103 press the inner surfaces of the bendable and deformable elastic pieces 67, the bending and deformation of the elastic pieces 67 can be regulated, an engagement force of the third engagement portions 69 and the second engagement portions 45 can be maintained, and the state where the frame-shaped portion 51 is inserted into the frame-shaped body portion 30 can be reliably maintained.
Further, in the embodiment, the protrusion ridges (the second protrusion ridges 71) extending in the insertion portion insertion direction F2 are provided on the outer surface of the elastic pieces 67. The second protrusion ridges 71 come into pressing contact with the inner surfaces of the frame-shaped body portion 30 when the frame-shaped portion 51 is inserted into the frame-shaped body portion 30 (see
According to the foregoing aspect, the second protrusion ridges 71 provided on the outer surfaces of the elastic pieces 67 come into pressing contact with the inner surface of the frame-shaped body portion 30 when the frame-shaped portion 51 is inserted into the frame-shaped body portion 30. Therefore, the elastic pieces 67 partially come into pressing contact with the inner surface of the frame-shaped body portion 30. As a result, an area of a portion to which vibration from the holding member 20 is transmitted can be reduced, compared to a case where the entire elastic pieces 67 come into pressing contact with the inner surface of the frame-shaped body portion 30. Therefore, since a spring constant of the anti-vibration member 50 can he lowered, the anti-vibration performance of the anti-vibration member 50 can be further improved.
By providing the second protrusion ridges 71 on the outer surfaces of the elastic pieces 67, it is possible to more reliably bring the outer surface of the frame-shaped portion 51 into pressing contact with the inner surface of the frame-shaped body portion 30.
Further, in the embodiment, the recessed groove 73 that has a recessed groove shape is formed at a portion between the protrusion ridge and the engagement portion (the second protrusion ridge 71 and the third engagement portion 69) on the outer surface of the elastic piece 67. When the frame-shaped portion 51 is inserted into the frame-shaped body portion 30, the recessed grooves 73 are separated from the inner surface (the inner surfaces of the walls 33) of the frame-shaped body portion 30 (see
According to the foregoing aspect, the recessed grooves 73 formed at portions between the second protrusion ridges 71 and the third engagement portions 69 are separated from the inner surface of the frame-shaped body portion 30 when the frame-shaped portion 51 is inserted into the frame-shaped body portion 30. Therefore, since the elastic pieces 67 can reliably and partially come into pressing contact with the inner surface of the frame-shaped body portion 30, the anti-vibration performance of the anti-vibration member 50 can be further improved.
By forming the recessed grooves 73, it is possible to bend and deform the elastic pieces 67 more easily. Therefore, even when the pressing protrusions 103 are provided in the fixing member 80, it is easy to insert the insertion portion 81 inside the frame-shaped portion 51. That is, there is a concern that the provision of the pressing protrusions 103 protruding outwards max make it difficult to insert the insertion portion 81 into the frame-shaped portion 51, but since the elastic pieces 67 are easily bent and deformed outwards, there is no problem in inserting the insertion portion 81 into the frame-shaped portion 51.
Further, in the embodiment, as illustrated in
Therefore, even when the twisting force is applied to the long member P held in the holding portion 21, the frame-shaped body portion 30 of the holding member 20 can be hindered from interfering with the flanges 95 of the fixing member 80. That is, even when the twisting force is applied to the long member P and the frame-shaped body portion 30 is to come into contact with the flanges 95, the frame-shaped body portion 30 comes into contact with the extension pieces 60 of the anti-vibration member 50 at first. Therefore, the frame-shaped body portion 30 is inhibited from coming into direct contact with the flanges 95.
As a result, in the holder 10, a transmission path of vibration hardly occurs without involving the anti-vibration member 50. Therefore, anti-vibration performance of the anti-vibration member 50 can be sufficiently achieved.
Even when the twisting force is applied to the long member P held in the holding portion 21 in the holder 10, anti-vibration performance of the anti-vibration member 50 can be more reliably achieved because of synergistic effects of the effect obtained by the structure as described above (see
A holder 10A tier a long member (hereinafter also simply referred to as the “holder 10A”) according to the second embodiment illustrated in
That is, as illustrated in
As illustrated in
Accordingly, the outer surface (the outer surfaces of the second protrusion ridges 71, 71) of the frame-shaped portion 51 comes into pressing contact with the inner surface (the inner surfaces of the protrusions 39, 39 of the pair of walls 33, 33) of the frame-shaped body portion 30, and the outer surface (the outer surfaces of the first protrusion ridges 65, 65) of the frame-shaped portion 51 comes into pressing contact with the inner surface (the inner surfaces of the pair of walls 31, 31) of the frame-shaped body portion 30.
That is, in the embodiment, the outer surface of the frame-shaped portion 51 comes into pressing contact with the inner surface of the walls 31 and 33 included in the frame-shaped body portion 30. As a result, even when a twisting force is applied to the long member P held in the holding portion 21 in various directions, tilting or the like of the frame-shaped body portion 30 can be flexibly inhibited effectively. Thus, the frame-shaped body portion 30 can be hindered from interfering with the fixing member 80 and anti-vibration performance of the anti-vibration member 50 can be sufficiently achieved.
In a holder 10B for a long member (hereinafter also simply referred to as the “holder 10B”) according to the third embodiment illustrated in
That is, an anti-vibration member 50B in the embodiment has a structure in which the pair of extension pieces 60, 60 are not included. As illustrated in
In the stale where the anti-vibration member 50B and the fixing member 80A are assembled in the holding member 20, the pressing protrusions 103, 103 provided in the second extension portions 88 and 89 press the inner surface (the inner surfaces of the distal ends of the pair of elastic pieces 67, 67) of the frame-shaped portion 51 and the pressing protrusions 107, 107 provided in the first extension portions 83, 83 press the inner surface (the inner surfaces of the pair of walls 53, 53) of the frame-shaped portion 51. In addition, the rear surfaces of the flanges 95 of the fixing member 80A come into contact with the pair of walls 53, 53 included in the frame-shaped portion 51 and the ends of the first protrusion ridges 65 protruding at the outer surfaces of the walls 53 on the one end 51a side, and the ends of the pair of walls 55, 55 included in the frame-shaped portion 51 on one end 51a side.
In the embodiment, as in the foregoing embodiments, when a twisting force is applied to the long member P held in the holding portion 21, tilting or the like of the frame-shaped body portion 30 can be inhibited and the frame-shaped body portion 30 can be hindered from interfering with the fixing member 80A, and anti-vibration performance of the anti-vibration member 50B can be sufficiently achieved.
The present invention is not limited to the foregoing embodiments, but may be modified in various modified embodiments within the scope of the gist of the present invention and these embodiments are also included in the scope of the present invention.
