This application claims priority to Japanese Patent Application No. 2019-207112, filed on Nov. 15, 2019. The entire disclosure of Japanese Patent Application No. 2019-207112 is hereby incorporated herein by reference.
The present invention relates to a fishing rod that includes a rear grip portion.
A fishing rod includes a rear grip portion at the rod end side of the fishing rod relative to a reel seat. In this conventional fishing rod, the rear grip portion is configured separately from the rod blank that forms a part of the rod. That is, the rear grip portion is placed on the outer periphery of the rod blank. For example, when an angler holds the fishing rod with their right hand, the angler can place their right arm on the rear grip portion when a fish is caught. The angler can support the fishing rod with their right palm and their right arm.
Additionally, in one configuration, a rear grip portion is integrally formed with a rod blank, as in Japanese Patent No. 6494568. When the rear grip portion is integrally formed with the rod blank in this way, the sensitivity transmitted from the fishing rod to the hand is improved.
It has been found that the conventional fishing rods have drawbacks and an improved rear grip section is desired. For example, when the rear grip section is separate from the rod blank, the sensitivity transmitted from the fishing rod to a hand is decreased. Also, some anglers hold the rear grip portion with the left hand and double-handed cast. However, it has been found that some rods have made the length of the rear grip portion to be short so as to trim the weight of the fishing rod. This shortened rear grip portion can cause difficulty in holding the rear grip portion with the left hand.
An object of the present invention is to provide a fishing rod with high sensitivity, reduced weight and a rear grip portion that is easy to grip.
The fishing rod according to the present invention has a rod blank. A reel can be attached to the lower side of the rod blank. The rod blank has a main portion and a rear grip portion at a rod end side relative to the reel. The rear grip portion is continuous to the rod end side of the main portion. An end surface of the rod blank on the rod end side is inclined such that a lower side of the rear grip portion extends farther in a direction of the rod end side than the upper side.
According to this configuration, the reel (for example, a spinning reel) is attached to the lower side of the rod blank, and thus the reel is located on the lower side of the fishing rod. When the fishing rod is held in the right hand, for example, double-handed casting can be performed by holding the rear grip portion with the left hand. The thumb of the left hand abuts the upper portion of the rear grip portion, and at least one finger from the index finger to the little finger of the left hand abuts the lower portion of the rear grip portion. It is preferable that two to four fingers from the index finger to the little finger of the left hand abut the lower portion of the rear grip portion, and it is more preferable that all of the fingers from the index finger to the little finger of the left hand abut the lower portion of the rear grip portion. Alternatively, it is more preferable that three fingers from the index finger to the ring finger of the left hand abut the lower portion of the rear grip portion.
As can be understood, the end surface of the rod blank on the rod end side is inclined such that the lower side of the rear grip portion extends farther in a direction of the rod end side than the upper side. that is, the lower portion of the rear grip portion extends more in the direction of the rod end side than the upper portion of the rear grip portion. Thus, it is possible to place many fingers on the lower portion of the rear grip portion, when holding the rear grip portion with the left hand. Thus, even when the length of the rear grip portion is shortened, the gripping force can be ensured.
A fishing rod according to another embodiment of the present invention has a rod blank. A reel can be attached to the upper side of the rod blank. The rod blank has a main portion and a rear grip portion at the rod end side relative to the reel. The rear grip portion is continuous to the rod end side of the main portion. An end surface of the rod blank on the rod end side is inclined such that a lower side of the rear grip portion extends farther in a direction of the rod end side than the upper side.
According to this configuration, the reel (for example, a double bearing reel) is attached to the upper side of the rod blank, and thus is located on the upper side of the fishing rod. As in the case of the above-mentioned fishing rod to which the reel is attached to its lower side, many fingers can be brought into contact with the lower portion of the rear grip portion when holding the rear grip portion with the left hand. Thus, even when the length of the rear grip portion is shortened, the gripping force can be ensured.
Preferably, the fishing rod has an end cap. The end cap is attached to the end of the rod blank on the rod end side. The end surface of the end cap on the rod end side is inclined such that the lower side extends farther in a direction of the rod end side than the upper side. According to this configuration, the fishing rod can be smoothly inserted into a rod holder or a fishing rod bag. Additionally, it is possible to easily grasp the orientation of the fishing rod in the circumferential direction, due to the end surface of the end cap on the rod end side.
Preferably, the end cap has a guard wall which projects to the rod end side at least in the lower portion of the periphery of the end surface of the end cap on the rod end side. The projection amount of the guard wall gradually increases towards the lower side. According to this configuration, the guard wall can effectively protect the lower portion of the end surface of the rod blank on the rod end side and also the lower portion of the end cap.
Preferably, the width of the guard wall gradually widens towards the lower side. According to this configuration, the guard wall can effectively protect the lower portion of the end surface of the rod blank on the rod end side and also the lower portion of the end cap.
In one embodiment, the end cap has a base surface on the end surface on the rod end side of the end cap. The guard wall is located around the base surface. The inclined angle of the base surface relative to the plane orthogonal to the centerline of the main portion is smaller than the inclined angle of the end surface on the rod end side of the guard wall relative to the orthogonal plane. According to this configuration, the guard wall can project with respect to the base surface and the projection amount of the guard wall can be increased towards the lower side.
The fishing rod according to an embodiment of the present invention has a rod blank and an end cap. A reel can be attached to the lower side of the rod blank. The end cap is attached to the end of the rod blank on the rod end side. The rod blank has a main portion and a rear grip portion at the rod end side relative to the reel. The rear grip portion is continuous to the rod end side of the main portion. A end surface of the end cap on the rod end side is inclined such that the lower side extends farther in a direction of the rod end side than the upper side.
According to this configuration, the reel (for example, a spinning reel) is attached to the lower side of the rod blank, and thus the spinning reel can be located on the lower side of the fishing rod. As in the above-mentioned fishing rod, it is possible to place many fingers on the lower portion of the rear grip portion, when holding the rear grip portion with the left hand. Also, one of the fingers can abut the lower portion of the end cap. For example, three fingers from the index finger to the ring finger of the left hand can abut the lower portion of the rear grip portion and the little finger can abut the lower portion of the end cap. Therefore, even when the length of the rear grip portion is shortened, the gripping force can be ensured.
Another embodiment of a fishing rod according to the present invention has a rod blank and an end cap. A reel can be attached to the upper side of the rod blank. The end cap is attached to the end of the rod blank on the rod end side. The rod blank has a main portion and a rear grip portion at the rod end side relative to the reel. The rear grip portion is continuous to the rod end side of the main portion. An end surface of the rod blank on the rod end side is inclined such that the lower side extends farther in a direction of the rod end side than the upper side.
According to this configuration, the reel (for example, a double bearing reel) is attached to the upper side of the rod blank, and thus the double bearing reel is located on the upper side of the fishing rod. As in the above-mentioned fishing rod, it is possible to place many fingers on the lower portion of the rear grip portion, when holding the rear grip portion with the left hand. Also, a finger can abut the lower portion of the end cap. For example, three fingers of the index finger to the ring finger of the left hand can abut the lower portion of the rear grip portion and the little finger can abut the lower portion of the end cap. Therefore, even when the length of the rear grip portion is shortened, the gripping force can be ensured.
As described above, it is possible to increase the sensitivity of the rear grip portion, to reduce the weight of the rear grip portion and to easily hold the rear grip portion.
A fishing rod according to one embodiment of the present invention will be described below with reference to
The direction of the centerline of the fishing rod is the longitudinal direction and the rod tip side is the front side and the rod end side is the rear side. The side of the reel mounting surface 13 is the lower side and the opposite side of the reel mounting surface 13 in the radial direction is the upper side.
The reel seat 1 is tubular is tubular and is attached to the rod body, generally by inserting the rod body into the seal seat 1. The reel seat 1 can also be referred to as a pipe seat. The reel seat 1 is immovably fixed at a predetermined position of the rod body by attaching the reel seat to the outer periphery of the rod body directly or via a tubular spacer.
The reel seat 1 includes a reel seat body 10, a movable hood 11 and a nut 12. The rod body is inserted into the reel seat body 10. The reel seat body 10 has the reel mounting surface 13 and a fixed hood 14. The fixed hood 14 is integrally formed with the reel seat body 10. The first leg part 101 of the reel leg 100 faces the front side and the second leg part 102 faces the rear side in the state in which the spinning reel 90 is attached to the reel seat 1. The fixed hood 14 holds the first leg part 101 of the reel leg 100. The movable hood 11 is movable in a back-and-force direction relative to the reel seat body 10. The movable hood 11 holds the second leg part 102 of the reel leg 100. The nut 12 is screwed on the reel seat body 10. The nut 12 moves the movable hood 11 in the back-and-forth direction and fixes the movable hood 11 on the desired position. In this embodiment, the nut 12 is located on the rear side of the reel seat body 10. However, the nut 12 can be located on the front side of the reel seat body 10.
The rod body comprises one rod blank or a plurality of rod blanks (rod body). In this embodiment, the rod body includes a first rod blank 2 and a second rod blank 3. The first rod blank 2 is located on the front side of the second rod blank 3. The first rod blank 2 and the second rod blank 3 are joined integrally to each other. For example, the first rod blank 2 and the second rod blank 3 are joined to each other, inside of the reel seat body 10. The first rod blank 2 and the second rod blank 3 are joined to form an overlapping portion which has a predetermined length, for example. Meanwhile, the first rod blank 2 and the second rod blank 3 can be detachably connected to each other.
The second rod blank 3 is formed in a hollow shape by winding prepreg on a mandrel and firing. Carbon fiber or glass fiber can be used as reinforcing fiber of the prepreg. The second rod blank 3 extends from the reel seat 1 towards the rear side. The second rod blank 3 extends to the rear end of the fishing rod. The second rod blank 3 has a main portion 20 and a rear grip portion 21. The main portion 20 and the rear grip portion 21 are integrally formed with the second rod blank 3. The front portion of the main portion 20 is located inside of the reel seat 1. The main portion 20 extends from the reel seat 1 towards the rear side. The main portion 20 is a cylinder. The centerline 4 of the main portion 20 is the centerline of the second rod blank 3 and the centerline of the fishing rod. The surface orthogonal to the centerline 4 of the main portion 20 is referred to as an orthogonal plane. The normal line of the orthogonal plane is the centerline 4 of the main portion 20. The orthogonal plane is orthogonal to the longitudinal direction. The cross-sectional surface in which the second rod blank 3 is cut along the orthogonal plane is referred to as a transverse sectional surface and the cross-sectional shape is referred to as a transverse sectional shape. The transverse sectional shape of the main portion 20 is a circular shape. The main portion 20 preferably has a straight shape with a substantially constant diameter.
The rear grip portion 21 is continuous to the rear side of the main portion 20. The arm of the hand holding the fishing rod can be placed on the rear grip portion 21 or the rear grip portion 21 can be held with the opposite hand from the hand holding the reel seat 1 when casting with both hands. In the following, the situation in which the fishing rod is held with the right hand will be described as an example. When holding the fishing rod with the right hand, the right arm (including the elbow) is placed on the rear grip portion 21. When casting with both hands, i.e., when performing a double-handed casting, the right hand holds the reel seat 1 and the left hand holds the rear grip portion 21.
The rear grip portion 21 extends to the rear end of the second rod blank 3. The rear grip portion 21 is thicker than the main portion 20. In other words, the rear grip portion 21 expands radially further than the main portion 20. The rear grip portion 21 is spaced apart from the reel seat 1 to the rear side. In this embodiment, the rear grip portion 21 is shorter than the main portion 20. The length of the rear grip portion 21 is long enough for the left hand to hold. The length of the rear grip portion 21 is preferably a length that corresponds to at least three or more fingers among the four fingers from the index finger to the little finger of a general size hand of an adult.
The transverse sectional shape of the rear grip portion 21 is a non-circular shape. The rear grip portion 21 increasingly gradually expands in the radial direction towards the rear side. The rear grip portion 21 has an expanded section which continues from the rear side of the main portion 20 and gradually expands towards the rear side and a straight section which continues to the rear side of the expanded section, extends up to the rear end of the rear grip portion 21 and maintains a constant shape without expanding towards the rear side. An end cap 6 which will be described later, is attached to the straight section. It is preferable for the rear grip portion 21 to have a straight section. However, the straight section can be omitted.
The transverse sectional shape of the rear grip portion 21 is shown in
The rear grip portion 21 includes a pair of left and right corners 31, an upper surface 30 and a lower surface. In this embodiment, the rear grip portion 21 has a pair of left and right corners 31, however, the rear grip portion 21 can have only one corner 31. Since a pair of left and right corners 31 are disposed on the rear grip portion 21, the entire circumference of the rear grip portion 21 is divided into two sections in the circumferential direction. The upper portion of the divided sections is the upper surface 30 and the lower portion is the lower surface. The lower surface is the section where the upper surface 30 is omitted from the entire circumference of the rear grip portion 21. The upper surface 30 is located between the pair of left and right corners 31 and positioned in the upper side of the circumference of the rear grip portion 21. The lower surface is located between the pair of the left and right corners 31 and positioned in the lower side of the circumference of the rear grip portion 21. The radius of curvature of the upper surface 30 in the circumferential direction is preferably different from the radius of curvature of the lower surface in the circumferential direction. The radius of curvature of the upper surface 30 in the circumferential direction is preferably larger than the radius of curvature of the lower surface in the circumferential direction.
The upper surface 30 is the upper surface of the rear grip portion 21. The corners 31 are formed respectively on both ends of the upper surface 30 in the circumferential direction. The arm of the hand holding the fishing rod, that is, the right hand can be placed on the upper surface 30. In the planar view such as
The corner 31 is the portion where the radius of curvature in the circumferential directions is locally small. The radius of curvature of the corner in the circumferential direction is the smallest of the entire circumference of the rear grip portion 21. The corner 31 is a streak that extends from the front side to the rear side. In the planar view, the corners 31 are located on the end portions in right-and-left direction. The distance between both corners 31 is the size and the width of the rear grip portion 21 in right-and-left direction. The distance between both corners 31 gradually increases towards the rear side. The outer periphery of the rear grip portion 21 is vertically separated by the left and right corners 31. Among the two portions of the outer periphery of the rear grip portion 21, that are vertically separated by the left and right corners 31, the upper portion is the upper surface 30. The rear grip portion 21 has a shape in which the width gradually decreases from the pair of corners 31 to the lowermost top 20a of the rear grip portion 21. The transverse sectional shape of the rear grip portion 21 is an inverted triangle. The lowermost top 20a of the rear grip portion 21 is the vertex of the lower side of the inverted triangle. In a transverse sectional view, the lowermost top 20a of the rear grip portion 21 has a distance R2 from the centerline 4 of the main portion 20 to the lowermost top 20a of the rear grip portion 21.
As shown in
A rear end surface 3a of the second rod blank 3 can be parallel to the orthogonal plane. However, in this embodiment, the rear end surface 3a of the second rod blank 3 is inclined in relative to the orthogonal plane. That is, the rear end surface 3a of the second rod blank 3 is an inclined surface. The rear end surface 3a of the second rod blank 3 is inclined such that the lower side is farther rearward than the upper side. In the following, the inclined angle relative to the orthogonal plane is simply referred to as an inclined angle. The inclined angle θ1 of the rear end surface 3a of the second rod blank 3 is, for example, 45 degrees or less.
The fishing rod has the end cap 6 on the rear end of the fishing rod. The end cap 6 is attached to the rear end portion of the second rod blank 3. The shape of the end cap 6 when viewed from the rear side corresponds to the transverse sectional shape of the rear end portion of the second rod blank 3. As shown in
The end cap 6 includes a cap main body 60 and a cover 61. The cap main body 60 is attached to the second rod blank 3 and the cover 61 is attached to the cap main body 60. The cap main body 60 is preferably made of hard synthetic resin or metal. The cover 61 is preferably softer than the cap main body 60. The cover 61 is preferably made of rubber.
It is preferable for the cap main body 60 to have a cylinder shape. As such, it is preferable for the cap main body 60 to be hollow. It is preferable that the front end of the cap main body 60 is open and the rear end of the cap main body 60 is closed. The cap main body 60 has an cylinder part 70 and an outer cylinder part 71. The cylinder part 70 is inserted inside of the rear end portion of the second rod blank 3. The transverse sectional shape of the cylinder part 70 corresponds to the transverse sectional shape of the rear end portion of the second rod blank 3. The transverse sectional shape of the cylinder part 70 is an inverted triangle. The cylinder part 70 holds the inner periphery of the rear end portion of the second rod blank 3 and prevents the rear end portion of the second rod blank 3 to be crushed and destroyed. The cylinder part 70 is a supporting section which supports the inner periphery of the rear end portion of the second rod blank 3. The cylinder part 70 is adhered to the inner periphery of the second rod blank 3. The front end surface 70a of the cylinder part 70 is inclined such that the upper side is more forward than the lower side. That is, the front end surface 70a of the cylinder part 70 is inclined similarly to the rear end surface 3a of the second rod blank 3. The front end surface 70a of the cylinder part 70 is parallel to the rear end surface 3a of the second rod blank 3. The upper portion of the front end surface 70a of the cylinder part 70 is located in front of the lower portion of the front end surface 70a of the cylinder part 70. The length of the cylinder part 70 is constant over the entire circumference. That is, the length of the portion of the end cap 6 that is inserted inside of the second rod blank 3 is constant over the entire circumference.
The outer cylinder part 71 is continuous to the rear side of the cylinder part 70. The outer cylinder part 71 projects to the rear side from the rear end portion of the second rod blank 3. A flange 72 is formed on the outer periphery of the front end of the outer cylinder part 71. The flange 72 projects outward in the radial direction. It is preferable for the flange 72 to be formed on the entire circumference of the outer cylinder part 71. The flange 72 abuts the rear end surface 3a of the second rod blank 3. Since the flange 72 abuts the rear end surface 3a of the second rod blank 3, the cap main body 60 is not inserted further into the second rod blank 3. The front surface of the flange 72 abuts the rear end surface 3a of the second rod blank 3. The front surface of the flange 72 corresponds to the inclination of the rear end surface 3a of the second rod blank 3, and is thus similarly inclined. The rear end surface 3a of the second rod blank 3 and the front surface of the flange 72 are in surface contact. The rear end surface 3a of the second rod blank 3 and the front surface of the flange 72 are parallel to each other. It is preferable that the flange 72 projects radially outward more than the outer periphery of the second rod blank 3. Since the flange 72 projects more than the outer periphery of the second rod blank 3, a damage to the rear end surface 3a of the second rod blank 3 is effectively prevented. The cover 61 is attached to the outer cylinder part 71 of the cap main body 60. The cover 61 is located rearward of the flange 72. The outer periphery of the rear portion of the outer cylinder part 71 is located one step inward with respect to the outer periphery of the front portion of the outer cylinder part 71. A body convex portion 73 is formed on the outer periphery of the rear end portion of the outer cylinder part 71. The body convex portion 73 projects radially outward. It is preferable that the body convex portion 73 is formed over the entire circumference. The cover 61 is latched on the body convex portion 73.
The shape of the cover 61 corresponds to the transverse sectional shape of the rear end portion of the second rod blank 3. The cover 61 is, as shown in
As shown in
The projection amount of the guard wall 83 to the rear side can be constant over the entire length of the guard wall 83. However, in this embodiment, the projection amount gradually increases from the upper portion to the lower portion of the guard wall 83. The projection amount of the guard wall 83 is at a maximum at the lowermost point 83a of the guard wall 83. The width of the guard wall 83 can be constant, however, in this embodiment, the width of the guard wall 83 gradually widens from the upper portion to the lower portion of the guard wall 83. The width of the guard wall 83 is at a maximum at the lowermost point 83a of the guard wall 83.
By forming the guard wall 83 on the periphery of the rear surface of the plate-shaped part 80, the rear surface of the plate-shaped part 80 is divided into a portion where the guard wall 83 is formed and a portion where the guard wall 83 is not formed. The portion where the guard wall 83 is not formed on the rear surface of the plate-shaped part 80 is a base surface 84. The rear surface of the plate-shaped part 80 is constructed from the base surface 84 and the rear surface of the guard wall 83. The guard wall 83 is located around the base surface 84. The base surface 84 can be used as a display surface for providing a selectable display unit. That is, a display unit can be disposed on the base surface 84. The configuration of the display unit can be any suitable configuration. For example, the display unit can be formed by integrally forming irregularities on the base surface 84. The display unit can be formed by printing. A display member, such as a display board, separately attached to the base surface 84 can be the display unit. The guard wall 83 projects rearward with respect to the base surface 84, and the base surface 84 is set back to the front side in relation to the guard wall 83. The base surface 84 is recessed on the front side in relation to the guard wall 83, such that the base surface 84 is guarded by the guard wall 83.
As shown in
The spinning reel 90 is attached to the fishing rod constructed as described above, as shown in
The pair of corners 31 is located radially outward relative to and higher than the top 20a of the main portion 20 the rearward of the rear grip portion 21. Meanwhile, the pair of corners 31 is the portion that is most distant from the centerline 4 of the main portion 20 in the radial direction, and more distant from the centerline 4 of the main portion 20 in the radial direction than the lowermost top 20a of the rear grip portion 21 in a transverse sectional view. For that reason, even if the main portion 20 of the second rod blank 3 is relatively thin, the right arm can be easily placed on the upper surface 30. Additionally, the rotation of the rear grip portion 21 in the circumferential direction can be easily suppressed by the right arm. Specifically, upward expansion amount B1 of the rear grip portion 21 is larger than the downward expansion amount B2 in the rearward of the rear grip portion 21. For that reason, even if the main portion 20 of the second rod blank 3 is relatively thin, the right arm can be easily placed on the upper surface 30.
When performing a double-handed casting, as shown in
In this manner, when the rear grip portion 21 is held by the left hand, it is possible to easily grasp the orientation of the fishing rod in the circumferential direction by the pair of corners 31. Also, the thumb can abut against the upper surface 30. As such, when performing a double-handed casting, the fishing rod can be easily aligned in a predetermined direction and the casting can be performed accurately. Additionally, the left hand is unlikely to be displaced on the rear grip portion 21 in the circumferential direction due to the corners. Thus, it is possible to hold the rear grip portion and to cast with a small force.
The rear end surface 3a of the second rod blank 3 is inclined such that the lower side is farther rearward than the upper side and the lowermost top 20a of the rear grip portion 21 extends more rearward than the upper surface 30. Therefore, even if the length of the rear grip portion 21 is short, it is possible to place many fingers on the lowermost top 20a of the rear grip portion 21. Meanwhile, by making the rear grip portion 21 short, it is possible to reduce the weight of the rear grip portion 21, and thus, the weight of the fishing rod can be reduced.
The rear surface 83b of the guard wall 83 of the end cap 6 is inclined such that the lower side is farther rearward than the upper side. As such, the fishing rod can be smoothly inserted into a rod holder or a fishing rod bag. Additionally, the end cap 6 is an inverted triangle and the end cap 6 thins towards the lowermost part of the end cap 6. That is, the lowermost part of the end cap 6 has a sharply pointed shape which is slanted towards the rear side and the lower side. As such, the rear end portion of the fishing rod can be smoothly inserted into the rod holder or the fishing rod bag. Also, since the rear surface 83b of the guard wall 83 of the end cap 6 is inclined, it is possible to easily grasp the orientation of the fishing rod in the circumferential direction.
The projection amount of the guard wall 83 gradually increases towards the lower side and is at a maximum at the lowermost point 83a of the guard wall 83, and thus, the guard wall 83 can effectively protect the lowermost point of the rear end surface 3a of the second rod blank 3. Also, the lowermost point of the end cap 6 can be effectively protected by the guard wall 83. The width of the guard wall 83 gradually widens towards the lower side and is at a maximum at the lowermost point 83a of the guard wall 83, and thus, the guard wall 83 can effectively protect the lowermost point of the rear end surface 3a of the second rod blank 3 and the lowermost point of the end cap 6.
The inclined angle θ3 of the base surface 84 is smaller than the inclined angle θ2 of the rear surface 83b of the guard wall 83, therefore, the projection amount of the guard wall 83 can be easily increased towards the lower side without excessively increasing the thickness. The front end surface 70a of the cylinder part 70 of the end cap 6 is inclined such that the lower side is farther rearward than the upper side, and thus, the weight of the cylinder part 70 can be reduced while the cylinder part 70 holds the second rod blank 3.
Also, as shown in
In some embodiments, the transverse sectional shape of the rear grip portion 21 can be circular. It is still preferable that the rear end surface 3a of the second rod blank 3 is inclined as shown in
When the rear end surface of the end cap 6 is an inclined surface inclined such that the lower side is farther rearward than the upper side, the rear end surface 3a of the second rod blank 3 can be an plane orthogonal to the centerline 4 of the main portion 20 without being inclined. Thus, even when the length of the rear grip portion 21 is shortened, the ring finger or the little finger, for example, can abut the lower portion of the end cap 6 and the short rear grip portion 21 can be supplemented with the lower portion of the end cap 6. The front end surface 70a of the cylinder part 70 of the end cap 6 can be inclined such that the upper side is farther rearward than the lower side or can be a plane orthogonal to the centerline 4 of the main portion 20.
