The present invention relates to a mounting body which can be mounted to a bolt body, and more particularly to a mounting body to a bolt body which can be easily and securely mounted to a position apart from an end portion of the bolt body.
In conventional, in the case of installing a cable rack (a receiving device) for arranging a wiring material and a piping material in a station or a plant, it is generally carried out to fix to a bolt body suspended from a ceiling (or buried in the ground) by means of a nut. Further, in the case of installing the other various plant materials in a building, it is carried out to fix the plant materials to a bolt body fixed to a construction thing of the building so as to install.
In particular, in the case that the plant materials are fixed to an intermediate position of the bolt body by the nut body, the fixation to the bolt body is achieved by clamping a “connection portion to the bolt body” in a “subject to be installed” such as the cable rack, the box or the like from front and rear sides (or from upper and lower sides) by a plurality of nut bodies. In specific as shown in
However, in order to fix the placed subject to the intermediate position of the long bolt body, it is necessary to rotate and move forward the nut body at a significant distance from an end portion of the bolt body. Accordingly, a very troublesome work is required for installing the placed subject.
In accordance with the present invention, since the “mounting portion” is integrally provided in the connection portion to the bolt body in the “placed subject” such as the cable rack, the box and the like, it is possible to mount to the bolt body only by applying the “mounting portion” from a side portion of the bolt body and applying a simple work.
On the other hand, the conventional “nut” is screwed forward in an axial direction of the bolt body by rotating and moving forward from one end of the bolt body. Here, in the case that the nut body or the like has already been screwed and fixed to a predetermined position and the other positions in the bolt body, it is impossible to rotate and move forward a new nut body into the fixed interval.
Accordingly, as shown in
Therefore, in accordance with the technique on the basis of the interposition type nut, since it is not necessary to rotate and move forward the nut to the bolt body from the end portion thereof, it is possible to horizontally mount from any positions of the bolt body, and it is possible to contribute to an improvement of an installing efficiency. Further, this structure can be applied to a position where both ends of the bolt body have been already supported, a position where the mounting position is frequently moved, and a position where the nut fails to be installed after the execution. Further, as shown in
However, in the interposition type nut mentioned above, since an extremely high accuracy is required in a stage of manufacturing the nut and a structure of the nut is complex, a unit price per one set of nut mentioned above becomes high. Accordingly, in the case that the “interposition type nut” mentioned above is frequently used, the execution cost is increased. Therefore, the “interposition type nut” is actually used only in a specific position for compensating for the conventional inexpensive nut. In other words, it is necessary to use the conventional inexpensive nut and the expensive interposition type nut together.
The present invention is made by taking the various problems in the prior art mentioned above into consideration, and inexpensively provides a “mounting body 100” and a “nut body 110” which can be easily mounted from a side portion of a bolt body 300. A description will be given of the “mounting body 100”.
First, the mounting body 100 in the present invention indicates a “receiving device 120 for a wiring material and a piping material” (refer to
The “mounting portion 10” mentioned above is provided as a part of the mounting body 100 corresponding to the mounted subject, the mounting portion 10 is provided with an engagement portion 20, an adjacent portion 30 provided in a leading end of the engagement portion 20, and an opening portion 70 moving the bolt body 300 into the engagement portion 20, and an engagement projection 21 engaging with an outer thread 310 of the bolt body 300 is provided in a protruding manner on one surface of the engagement portion 20.
Further, the mounting portion 10 in the present invention is moved close to the bolt body 300 by applying the “engagement portion 20” of the mounting portion 10 to the outer surface of the bolt body 300 corresponding to the mounted subject from a side portion thereof, and thereafter, the engagement portion 20 is plastically deformed by relatively moving the adjacent portions 30 close to each other, whereby the engagement portion 20 is arranged along the outer surface of the bolt body 300. It is possible to maintain a state in which the engagement projection 21 protruded on the surface of the engagement portion 20 is engaged with an outer thread 310 of the bolt body 300, by arranging (closely attaching) the engagement portion 20 along the outer surface of the bolt body 300.
In other words, it is possible to engage the mounting portion 10 with the outer thread 310 of the bolt body 300, and it is possible to mount the mounting body 100 corresponding to the mounted subject to the outer surface of the bolt body 300.
In other words, in accordance with the present invention, it is possible to maintain a state in which the engagement projection 21 is engaged with the outer thread 310 of the bolt body 300, only by plastically deforming the engagement portion 20 in connection with the mounting portion 10, and it is possible to mount the mounting body 100 to the bolt body 300.
In this case, as mentioned above, since the engagement portion 20 is plastically deformed after being applied and arranged from the side portion of the outer surface in the bolt body 300, it is possible to mount the mounting body 100 regardless of whether the end portion or the intermediate portion of the bolt body 300.
Subsequently, a description will be first given of the engagement portion 20, with respect to the structure of the mounting portion 10.
The engagement portion 20 is structured such that the engagement portion 20 itself is plastically deformed, thereby being brought into contact with (closely attached to) the bolt body 300 in connection with the mounted subject so as to clamp the bolt body 300. A specific structure of the engagement portion 20 is not particularly limited, however, there can be considered, for example, a structure in which a flat plate is bent and a pair of band-shaped members are provided so as to stand face to face, as shown in
The opening portion 70 is formed between a pair of band-shaped members, and the bolt body 300 in accordance with the mounted subject is moved forward from the opening portion 70 so as to be plastically deformed. In the case that the engagement portion 20 is formed by providing “a pair of band-shaped members” so as to stand face to face as shown in
Further, the engagement portion 20 is provided with an “engagement projection 21” engaging with the outer thread 310 of the bolt body 300 in a protruding manner, and the “adjacent portion 30” is formed by folding the leading end.
In the case that the bolt body 300 is clamped by bringing the engagement portion 20 in to contact with the bolt body 300 (closing attaching the engagement portion 20 to the bolt body 300), the engagement portion 20 is plastically deformed, and the engagement projection 21 provided in the engagement portion 20 in a protruding manner is engaged with the outer thread 310 of the bolt body 300. The engagement projection 21 is engaged with the outer thread 310 of the bolt body 300, whereby it is possible to prevent the mounting body 100 corresponding to the mounted subject from being displaced with respect to the axial direction of the bolt body 300.
The engagement portion 20 may employ every materials as far as the material can be plastically deformed itself. In specific, it is considered to be preferable that the engagement portion 20 is formed by a metal (a steel plate) and a deformed state can be maintained after being deformed. Accordingly, it is possible to maintain the “state in which the engagement projection 21 is engaged with the outer thread 310 of the bolt body 300” mentioned above, by plastically deforming the engagement portion 20, and it is possible to continuously mount the mounting body 100 corresponding to the mounted subject to the bolt body 300.
It is possible to plastically deform the engagement portion 20 mentioned above, by relatively moving the “adjacent portion 30” provided in the leading end side of the engagement portion 20 close to each other. The “adjacent portion 30 ” may be formed as a grip piece corresponding to a “gripping portion” at a time of plastically deforming the engagement portion 20. In other words, as shown in
Further, the “adjacent portion 30” mentioned above may be previously provided so as to protrude toward a slightly leading end direction (a lower side in
In this case, the “engagement projection 21” mentioned above is engaged with the outer thread 310 of the bolt body 300, and the following structure can be considered as a specific structure thereof. In other words, the structure is made such that one or two or more projection (the engagement projection 21) is provided in a protruding manner on the “contact surface” with the outer surface of the bolt body 300 in accordance with the mounted subject, and the projection is engaged with the outer thread 310 of the bolt body 300. In this case, the structure may be made such that a groove 22 is spirally inscribed on the “contact surface” mentioned above, and the spirally inscribed surface is engaged with the outer thread 310 of the bolt body 300. In other words, as shown in each of the drawings, since an entire of the spirally inscribed surface can be engaged with the outer thread 310 of the bolt 300 by spirally inscribing the groove 22 on the engagement surface, it is possible to strongly and securely engage the engagement portion 20 with the bolt body 300. At this time, it is considered to be preferable that the “groove 22” is spirally inscribed at a pitch corresponding to the outer thread 310 of the bolt body 300 in accordance with the mounted subject. In the case of employing the structure mentioned above, since the entire of the spirally inscribed surface is engaged with the outer thread 310 of the bolt body 300, it is possible to effectively prevent the mounting body 100 from being displaced in the axial direction of the bolt body 300.
In this case, a time when a the engagement projection 21 is engaged with the outer thread 310 of the bolt body is not limited to a time before the engagement portion 20 is plastically deformed or a time after the engagement portion 20 is plastically deformed.
In other words, for example, in the case that the mounting body 100 (the nut body 110) shown in
On the other hand, for example, in the mounting body 100 (the nut body 110) which is formed slightly larger than a diameter of the bolt body 300, as shown in
Further, in the present invention, the mounted subject is the bolt body 300, and the engagement projection 21 of the engagement portion 20 is engaged with the outer thread 310 of the bolt body 300 as mentioned above. Accordingly, it is possible to move the mounting body 100 with respect to the axial direction of the bolt body 300 by rotating the bolt body 300 (or rotating with respect to the bolt body 300) in a state in which the “engagement projection 21” in the mounting body 100 is engaged with the outer thread 310 of the bolt body 300.
In other words, it is possible to move (elevate) the mounting body 100 in the axial direction of the bolt body 300, by rotating the bolt body 300, in a state in which the mounting body 100 (for example, the “wiring material and piping material receiving device 120”, the “wiring box 130 and the like corresponding to the mounted subject is bonded to the bolt body 300 such as the “suspended bolt” suspended from the ceiling or the “support bolt” stood by fixing one end to the floor surface. Accordingly, in the case of changing the mounting position of the mounting body 100 to an optional position in an entire length of the bolt body 300, the mounting body 300 can be moved by rotating the mounting body 100 with respect to the bolt body 300 in a state in which the mounting body 100 is mounted to the bolt body 300, or rotating the bolt body 300.
Further, the “engagement portion 20” mentioned above may be constituted by a multi-layer structure. In other words, the “engagement portion 20 in accordance with the multi-layer structure” has an “inner member 62” and an “outer member 61”, as shown in
In this case, since the inner member 62 is structured by the plastic material, the inner member 62 is pressed to the outer thread 310 of the bolt body 300, thereby eating into the outer thread 310 of the bolt body 300. In accordance that the inner member 62 eats into the outer surface of the bolt body 300, the surface in the inner member 62 which is brought into contact with the outer thread 310 of the bolt body 300 is deformed along the outer thread 310 of the bolt body 300. Accordingly, the engagement projection 21 is formed on the surface in the inner member 62 which is brought into contact with the outer thread 310 of the bolt body 300, and the engagement projection 21 is engaged with the outer thread 310 of the bolt body 300. Accordingly, it is possible to control the axial movement with respect to the bolt body 300, and it is possible to mount the mounting body 100 provided with the mounting portion 10 without moving in the axial direction with respect to the bolt body 300.
Next, a description is given of the “adjacent portions 30”. The “adjacent portions 30” are provided in the leading end side of the engagement portion 20 mentioned above, and correspond to the portions which are relatively close to each other by plastically deforming the engagement portion 20.
Further, the adjacent portion 30 makes a mounting work easy by being gripped as a “grip piece” at a time of plastically deforming the engagement portion 20. In other words, in order to plastically deform the engagement portion 20, the pinching operation by the pinching tool P can be easily and securely achieved, by gripping the adjacent portion 30 by the pinching tool P such as the pincher or the like, as shown in
As a specific aspect of the “adjacent portion 30”, it is considered to employ “a pair of adjacent portions 30” or “a piece of adjacent portion 30”.
First, “a pair of adjacent portions 30” are structured such that “a pair of” engagement portions 20 of the mounting portion 10 are provided so as to relatively stand face to face, and “a pair of adjacent portions 30” are formed by providing the “adjacent portion 30” in each of the leading end sides of the engagement portions 20. Further, the engagement portion 20 is plastically deformed by moving forward the bolt body to the opening portion 70 between the adjacent portions 30 and there after moving the adjacent portions 30 close to each other.
Next, “a piece of adjacent portion 30” is formed by folding the leading end of the engagement portion 20 to an outer side. In this case, the engagement portion 20 is formed in an approximately U-shaped cross section by extending from a base end of the mounting portion 10 in the mounting body 100. Further, in order to move the adjacent portion 30 formed in the leading end of the engagement portion 20 close to a portion near the “base end of the engagement portion 20” in an approximately close contact state, after moving forward the bolt body into an inner side of the engagement portion 20 having the U-shaped cross section from the opening portion 70, the engagement portion 20 is plastically deformed.
Further, in order to engage the engagement projection 21 with the outer thread 310 of the bolt body 300, the engagement portion 20 may be plastically deformed until the “adjacent portions 30” provided in the leading end side of the engagement portion 20 are approximately close contacted with each other. In other words, the “engagement projection 21” provided in a protruding manner in the engagement portion 20 is engaged with the outer thread 310 of the bolt body 300, by clamping the adjacent portions 30 by means of the pinching tool P such as the pincher or the like until the “adjacent portions 30” are relatively in an approximately contact state.
Accordingly, the “adjacent portions 30” are relatively in the approximately close contact state by finishing the engagement with the outer thread 310 of the bolt body 300 by means of the engagement projection 21. Therefore, the opening portion 70 (refer to
Further, in the case that the engagement is finished by making the adjacent portions 30 in the approximately close contact state with each other, as mentioned above, a target for finishing the engagement is set, so that it is possible to necessarily and sufficiently deform the engagement portion 20 plastically. Accordingly, it is possible to prevent the bolt body 300 from coming off from the mounting portion 10.
On the other hand, the mounting body 100 in accordance with the present invention may be structured such that the mounting body 100 is provided with a “holding portion 50” for holding a secondary mounting body 200, and the mounting body is mounted to the bolt body 300 in a state in which the “holding portion 50” holds the “secondary mounting body 200”, whereby the “secondary mounting body 200” is mounted to the bolt body 300. The “secondary mounting body 200” is structured such as to be placed in the bolt body 300 and be provided with no mounting portion 10. In specific, as shown in
In order to mount the secondary mounting body 200 to the bolt body 300 in accordance with the mounted subject, the secondary mounting body 200 can be mounted to the bolt body 300, by mounting to the bolt body 300 while keeping the state in which the secondary mounting body 200 is held by the holding portion 50 provided in the mounting body 100.
The holding portion 50 may employ any methods or structures. In specific, for example, as shown in
On the other hand, the mounting body 100 in accordance with the present invention may be provided with a “held portion 51” in which the secondary mounting body 200 is placed, and may be structured such that the secondary mounting body 200 can be placed in the “held portion 51” after mounting (or “before mounting” the mounting body 100 to the bolt body 300. In specific, as shown in
In other words, in accordance with the mounting body 100 provided with the held portion 51, it is possible to easily place a conventionally provided “pedestal” to which various materials can be fixed, only by bringing the engagement portion 20 into contact with the bolt body 300. In this case, the fixing method between the held portion 51 and the secondary mounting body 200 is not limited to the “screwing” mentioned above, and the held portion 51 and the secondary mounting body 200 can be fixed (placed) in accordance with every methods such as a “fitting method”, a “hooking method”, an “adhering method” and the like which have been conventionally proposed.
Further, the mounting body 100 in accordance with the present invention maybe structured such that the mounting portion 10 is provided with a “deviation preventing portion 40 or the like”. The “deviation preventing portion 40 or the like” is structured such as to maintain a state in which the “engagement portion 20” mentioned above is plastically deformed along the outer surface of the bolt body 300. In other words, it is possible to prevent the adjacent portions 30 which are relatively moved close to each other by plastically deforming the engagement portion 20, from being again deviated from each other, and it is by extension possible to maintain a state in which the engagement projection 21 provided in a protruding manner in the engagement portion 20 is engaged with the outer thread 310 of the bolt body 300 (hereinafter, refer to a “deviation preventing effect (opening stop)”.
The deviation preventing portion 40 or the like indicates the “deviation preventing portion 40” and a “deviation preventing member 41” as already mentioned, and a description is given below of each of them.
First, the “deviation preventing portion 40” is integrally structured with the mounting portion 10 in the mounting body 100, and achieves the “deviation preventing effect (opening stop) ”. In other words, it is possible to finish the plastic deformation of the engagement portion” to the “locking by the deviation preventing portion”, on the basis of one clamping work, by integrally structuring the deviation preventing portion 40 with the mounting portion 10. In specific, as shown in
On the other hand, the “deviation preventing member 41” is structured as an independent member from the mounting portion 10, and achieves the “deviation preventing effect (opening stop)” mentioned above. In specific, as shown in FIGS. 7 to 16, there can be considered that an independent member from the mounting portion 10 is structured such as to be locked with the outer end of the “engagement portion 20” or the “adjacent portions 30”. In the case that the “opening stop” is achieved by the “deviation preventing member 41”, first, the engagement portion 20 is plastically deformed and the adjacent portions 30 are relatively close to each other, by clamping the adjacent portions 30 by the pinching tool P such as the pincher or the like. Further, in order to prevent the adjacent portions 30 moving close to each other from being again deviated, the deviation preventing member 41 locks so as to cover the plastically deformed “outer end of the engagement portion 20” or the “relatively moving close adjacent portions 30”.
In this case, the deviation preventing member 41 may be structured, as shown in
In accordance with the structure mentioned above, it is possible to prevent the adjacent portions 30 which are once moved close to each other, from being again expanded, on the basis of the provision of the “deviation preventing portion 40 or the like” in the mounting portion 10, and it is by extension possible to maintain the mounting state to the bolt body 300 by the mounting portion 10 (or the engagement with the outer thread 310 of the bolt body 300 by the engagement projection 21) completely.
Next, a description is given of a manufacturing process of the mounting portion 10 of the mounting body 100 in accordance with the present invention.
There can be considered that the mounting portion 10 in the present invention is structured, as shown in FIGS. 22 to 24, by applying a press molding to a steel plate. In other words, there can be considered that the mounting portion 10 having the approximately U-shaped cross section is formed by arranging the steel plate on a depressed metal mold and pressing the steel plate by a “punch” from the above. In this case, in the case that the engagement projection 21 in the engagement portion 20 is constituted by a “groove 22 having a fixed pitch (that is, a spirally inscribed surface)”, it is considered to be preferable to structure the “spirally inscribed surface” by forming a plurality of “grooves 22” having a fixed pitch in the steel plate, prior to the press molding. In other words it is considered to be preferable to form the “groove 22 having a fixed pitch (that is, the spirally inscribed surface)” as shown in
On the other hand, the structure may be made such that the “groove 22 (the spirally inscribed surface)” maybe formed at the same time of applying the press molding to the steel plate, in spite of previously forming the engagement projection as mentioned above. In other words, it is possible to form a “threaded groove-shaped engagement projection 21 (the groove 22)” at a position corresponding to the inner side of the engagement portion, by pressing the steel plate into the metal mold as shown in FIGS. 22 to 24, by means of a “punch” provided with a spirally inscribed blade in a leading end.
Next, a description is given of the “nut body 110”. The nut body 110 is a nut body 110 which is screwed from a side surface of the bolt body 300, and has the “engagement portion 20” and the “adjacent portions 30”. In other words, in the present invention, the “nut body 110” is structured such that the “mounting portion 10” in the mounting body 100 is constructed as an independent member and is mounted to the outer surface of the bolt body 300, as the “nut body 110”.
The nut body 110 can be mounted to the bolt body by applying to an intermediate portion of the bolt body in which both ends are already fixed and closed, from a side portion so as to plastically deform, as shown in
In this case, since each of the constituting elements in the “nut body 110” is the same as that in the “mounting body 100” mentioned above, a description thereof is omitted.
Further, FIGS. 1 to 20 show the “nut body 110”. It is possible to structure a “receiving device 120”, a “box 130” or the like corresponding to the mounting body, provided with the “deviation preventing member 41”, the “double-structure engagement portion 20” or the like, by integrally structuring the nut body 110 as the “mounting portion 10” in the mounting body 100 such as the “receiving device 120” or the like.
In accordance with the structure mentioned above, when mounting the receiving device 120 or the like corresponding to the mounting body to the bolt body 300 in accordance with the mounted subject, the mounting operation is finished by first moving the engagement portion 20 in accordance with the mounting portion 10 close to the outer surface of the bolt body 300 from the side portion so as to arrange there, thereafter plastically deforming the engagement portion 20 (by clamping by means of the pinching tool P such as the pincher or the like), and engaging the engagement projection 21 provided in a protruding manner in the engagement portion 20 with the outer thread 310 of the bolt body 300.
Accordingly, it is possible to mount the receiving device 120 or the like corresponding to the mounting body 100, only by applying the receiving device 120 or the like to the “bolt body 300” in accordance with the mounted subject from the side portion and applying a simple work thereto. In this case, as mentioned above, since the engagement portion 20 is plastically deformed by applying the engagement portion 20 from the side portion of the outer surface in the bolt body 300, it is possible to mount the receiving device 120 or the like regardless of whether the end portion or the intermediate portion of the bolt body 300.
(Embodiment 1)
In order to mount the nut body 110 of the present embodiment to the bolt body 300, the bolt body 300 is first moved forward into the engagement portion 20 from the opening portion 70.

The “deviation preventing portion 40” is integrally formed with the nut body 110, and prevents the adjacent portions 30 provided in the leading end of the mounting portion 10 from being deviated (expanded) from each other (hereinafter, refer to as a “deviation preventing effect”). In other words, the adjacent portions 30 are deviated from each other, thereby preventing the mounting to the bolt body 300 by the nut body 110 from being cancelled.
In the present embodiment, in the case that “a pair of adjacent portions 30” are provided in the leading end of the engagement portion 20, a hook-shaped member is integrally provided only in one adjacent portion 30 in a pair of adjacent portions 30, and another adjacent portion 30 is locked to the hook-shaped member provided in the one adjacent portion 30. In the case of mounting to the bolt body 300 by the mounting portion 10 provided with the hook-shaped member, it is possible to prevent the adjacent portions 30 from being deviated from each other by locking one of the adjacent portions 30 to the hook-shape member, at a time of relatively moving the adjacent portions 30 provided in the leading end of the engagement portion 20 to each other in order to plastically deform the engagement portion 20 along the outer surface of the bolt body 300.
In this case, the mounting body 100 in the present embodiment is structured such that the “deviation preventing effect” is generated by the “deviation preventing portion 40” integrally provided with the nut body 110, however, the deviation preventing portion 40 is not limited to a structure which is integrally formed with respect to the nut body 110.

At this time, the end portion of the deviation preventing member 41 enters into the “notch” of the adjacent portions 30”. Further, a pair of “pawls” are formed in the end portion of the deviation preventing member 41, and the “pawls” are engaged with the adjacent portions 30. Accordingly, it is possible to prevent the deviation preventing member 41 from falling off from the nut body 110, on the basis of a locking by these two points.
In this case, it is necessary to insert the deviation preventing member 41 shown in
(Embodiment 3)
The nut body 110 of the presented embodiment is provided with an “engagement portion 20 in accordance with a long size”, and is structured such that a pair of adjacent portions 30 in accordance with a short size are provided in both ends of the engagement portion 20 so as to stand face to face.
Since the engagement projection 21 (the groove 22) is provided in a protruding manner in an inner side of the engagement portion 20 all along an entire length, the engagement projection 21 (the groove 22) is engaged with a lot of outer threads in the bolt body, so that it is possible to more securely prevent a displacement which may be generated in an axial direction of the bolt body.
Further, since the adjacent portions 30 provided in the leading end of the engagement portion 20 are formed short, it is possible to easily clamp by a tool in order to plastically deform the “engagement portion 20 in accordance with the long size” mentioned above.
In this case, the nut body 110 of the present embodiment may be structured, as described in the embodiment 2 mentioned above, such that the deviation preventing portion 40 or the like is provided so as to generate the deviation preventing effect.
(Embodiment 4)
The nut body 110 of the present embodiment is provided with the “engagement portion 20 in accordance with the long size”, and is structured such that a pair of adjacent portions 30 are provided in an intermediate portion of the engagement portion 20 so as to stand face to face with each other. Since the engagement projection 21 (the groove 22), is provided in a protruding manner in the inner side of the engagement portion 20 all along an entire length, the engagement projection 21 (the groove 22) is engaged with a lot of outer threads in the bolt body, so that it is possible to more securely prevent a displacement which may be generated in the axial direction of the bolt body.
Further, in the nut body 110 of the present embodiment, since the adjacent portion 30 is provided only in one position in a center of the engagement portion 20 in a longitudinal direction, it is possible to plastically deform the engagement portion 20 all along an entire length, by clamping the “one adjacent portion” by the pinching tool P. Further, even in the case that the “engagement portion 20” is operated so as to return to a shape before being plastically deformed (that is, such that the adjacent portion 30 is expanded), a pair of adjacent portions 30 which are relatively moved close to each other are pinched by the “deviation preventing member 41”, so that it is possible to securely prevent a pair of adjacent portions 30 from being again expanded.
In this case, the engagement projection 21 may not be provided in a protruding manner in an inner side of a “band-shapedportion (narrowportion)” in accordance with the engagement portion 20 in which a pair of adjacent portions 30 are formed (refer to
(Embodiment 5)
The nut body 110 of the present embodiment is structured such that a pair of adjacent portions 30 are provided in a protruding manner in the leading end portion of the engagement portion 20 so as to stand face to face with each other, and an engagement projection 21 (a groove 22) is provided in a protruding manner in an inner side of the engagement portion 20 all along an entire length thereof. Accordingly, since the engagement projection 21 (the groove 22) is engaged with a lot of outer threads in the bolt body, it is possible to prevent a displacement which may be generated in the axial direction of the bolt body.
Further, a “slit” is formed in a back surface of the nut body 110 (that is, an intermediate portion of the engagement portions 20 which stand face to face with each other. Accordingly, since it is possible to substantially shorten a dimension in a longitudinal direction in the plastically deformed engagement portion 20, it is possible to plastically deform the “engagement portion 20 in accordance with the long size” even by a small force. This is particularly effective in the case that the engagement portion 20 is formed by the long size.
