Description

  The present invention relates to a fishing rod provided with a reel seat on which a rod is detachably mounted.

  There are various types of fishing rods depending on the application, and some of them have a telescopic marine structure (see, for example, Patent Document 1). The fishing rod described in Patent Document 1 includes a small-diameter housing and a large-diameter housing that fits in the small-diameter housing so as to be freely retractable. At the front and rear end portions of the small-diameter housing and the large-diameter housing, joint portions that are joined to each other are formed.

  This fishing rod includes an elastic holding body in contact with the outer peripheral surface of the small-diameter rod on the inner peripheral surface of the large-diameter rod that forms the joint portion. As a result, even if the outer diameter of the outer peripheral surface of the end portion of the small-diameter housing is slightly different from the reference size, the elastic holder absorbs the difference in the outer-diameter size due to its elastic deflection, and the small-diameter housing retreats. Maintain state.

In addition, the fishing rod includes a retaining member that is in close contact with the outer peripheral surface of the small-diameter rod at the rear end of the large-diameter rod that forms the joint portion.
Japanese Utility Model Publication No.4-212260

  The elastic holding body and retainer of Patent Document 1 hold the small diameter casing in a predetermined position by being in close contact with the outer peripheral surface of the small diameter casing. That is, a frictional resistance acts between the elastic holding body and the retaining member and the small diameter casing, and both are engaged by this frictional resistance.

  The present inventors have considered a fishing rod in which the end portion of the rod is directly inserted into the mounting hole that opens in the reel sheet and joined. It is conceivable that an elastic member is provided on the inner peripheral surface of the mounting hole, and the heel is joined by a frictional resistance between the elastic member and the end of the heel. There is a case where the engagement force between and does not increase so much. Since a large force may be applied to the joint portion between the reel sheet and the collar, it is preferable that the engagement force between the reel sheet and the collar is large.

  An object of the present invention is to obtain a fishing rod capable of firmly fixing an end portion of a rod inserted into a mounting hole of a reel sheet.

  In order to achieve the above object, a fishing rod according to one embodiment of the present invention includes a rod and a metal reel sheet having an opening in which an end of the rod is detachably inserted. The fishing rod includes a cylindrical elastic member having an outer peripheral surface that is in contact with an inner peripheral surface of the mounting hole and an inner peripheral surface that surrounds an end of the rod inserted into the mounting hole.

  Between the opening end of the mounting hole and the elastic member, there is provided a diameter expansion allowable region where the inner peripheral surface of the mounting hole and the outer peripheral surface of the elastic member are separated from each other. The end portion of the flange is joined to the reel sheet by elastically deforming the elastic member so as to expand the diameter toward the inside of the diameter expansion allowable region at the opening end portion of the mounting hole.

  According to this configuration, the elastic member into which the end portion of the flange is inserted can be elastically deformed in the diameter increasing direction inside the mounting hole. The elastic member elastically deformed in the diameter increasing direction fastens the end of the heel in the direction of the diameter reduction, so that the end of the heel is firmly fixed.

  Hereinafter, a fishing rod 1 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 discloses a fishing rod 1 such as a casting rod. The fishing rod 1 includes a rod 2 and a handle member 3 to which the rod 2 is attached.

  The rod 2 is provided with a plurality of fishing line guides 4 that guide the fishing line and prevent the fishing line from adhering to the outer peripheral surface of the rod 2. The plurality of fishing line guides 4 are provided on the outer peripheral surface of the rod 2 at a predetermined interval toward the tip of the fishing rod 1. Further, a top guide 5 is provided at the tip of the heel 2. Note that the cocoon 2 is not limited to a single cocoon but may be a combination of two or more cocoons.

  An example of the ridge 2 is made of, for example, a fiber reinforced resin material in which a reinforced fiber is impregnated with a synthetic resin material. The material of the ridge 2 is not limited to the above example. Moreover, although the collar 2 which concerns on this embodiment is formed in the hollow cylinder shape, for example, it may replace with this and may form in a solid shape.

  On the other hand, the handle member 3 includes a reel sheet 11 and a grip portion 12 provided behind the reel sheet 11. In the present embodiment, the front, rear, left, and right are defined by looking at the tip of the heel 2 from the reel sheet 11. The reel sheet 11 is formed as a substantially cylindrical member having an outer diameter of about 20 mm to 30 mm, for example.

  An example of the reel sheet 11 is made of a metal material such as aluminum alloy, brass, stainless steel, magnesium alloy, or titanium alloy. The material of the reel sheet 11 is not limited to the above example, and various metal materials can be selectively used as appropriate.

  As shown in FIG. 2, the central portion in the longitudinal direction (that is, the front-rear direction) of the reel sheet 11 has a flat structure having a large width dimension in comparison with the vertical direction, and the fishing reel 13 is attached. A reel mounting portion 14 is formed. The grip portion 12 is provided with a grip member 15 made of, for example, wood or hard synthetic resin. The grip member 15 includes a trigger 16 that protrudes downward from the lower portion of the reel sheet 11.

  An attachment portion 21 to which the collar 2 is attached is provided at the tip end portion of the reel sheet 11 (that is, the end portion opposite to the grip portion 12). The attachment portion 21 is formed in a cylindrical shape, for example, and extends from the reel sheet 11 as an integral member.

  As shown in FIG. 3, the attachment portion 21 is provided with a mounting hole 23 into which the butt end portion 22 of the heel 2 is detachably inserted. The mounting hole 23 has an opening 23 c that opens toward the front of the reel sheet 11 (that is, the direction opposite to the grip portion 12) and opens to the outside of the reel sheet 11. The mounting hole 23 extends from the opening 23 c into the attachment portion 21 along the longitudinal direction of the reel sheet 11.

  The axial direction of the mounting hole 23 coincides with the longitudinal direction of the reel sheet 11. The axial length of the mounting hole 23 is, for example, about 50 mm to 70 mm in order to ensure the mounting strength of the flange 2. The mounting hole 23 has, for example, a cylindrical inner peripheral surface 23 a and a bottom wall 26 provided at the innermost part along the axial direction of the mounting hole 23. The bottom wall 26 closes the innermost part of the mounting hole 23. The inner peripheral surface 23 a has an opening end 24 adjacent to the opening 23 c, and a bottom end 25 adjacent to the bottom wall 26 while being an end opposite to the opening end 24.

  As shown in FIG. 3, an elastic member 31 that fits and holds the buttock portion 22 is provided inside the mounting hole 23. The elastic member 31 is formed in a cylindrical shape along the inner peripheral surface 23 a of the mounting hole 23. That is, the elastic member 31 is formed in a cylindrical shape having an inner peripheral surface 31a and an outer peripheral surface 31b. The outer peripheral surface 31 b is in contact with the inner peripheral surface 23 a of the mounting hole 23. The inner peripheral surface 31 a surrounds the buttock portion 22 inserted into the mounting hole 23 and is in contact with the outer peripheral surface 22 b of the buttock portion 22. The elastic member 31 according to the present embodiment is provided continuously from the opening end 24 to the bottom end 25 of the mounting hole 23 along the axial direction, for example.

  More specifically, the elastic member 31 is continuously provided from the opening 23 c of the mounting hole 23 to the edge 23 d of the inner peripheral surface 23 a adjacent to the bottom wall 26. That is, the elastic member 31 covers the inner peripheral surface 23 a of the mounting hole 23 over the entire length along the axial direction of the mounting hole 23. Thus, when the buttock portion 22 is inserted into the mounting hole 23, the elastic member 31 is interposed between the inner peripheral surface 23 a of the mounting hole 23 and the outer peripheral surface 22 b of the buttock portion 22.

  The elastic member 31 has an opening 42 that opens toward the outside of the reel sheet 11. The opening 42 is continuous with the inner peripheral surface 31 a, and the buttock portion 22 is inserted into the elastic member 31 through the opening 42. The opening 42 is chamfered with, for example, R or C. If the opening 42 is chamfered, stress can be prevented from concentrating on the opening 42 when the elastic member 31 described later is elastically deformed, and damage to the fishing rod 1 can be avoided.

  The elastic member 31 has elasticity and is made of a material that is softer than the reel sheet 11. An example of the elastic member 31 is, for example, a carbon pipe, a glass pipe, or a synthetic resin pipe. The material of the elastic member 31 is not limited to the above example, and various materials can be selectively used as appropriate.

  If the reel sheet 11 formed of, for example, an aluminum alloy is used for a long period of time without providing the elastic member 31, there is a possibility that electrolytic corrosion may occur at the contact portion between the directly joined scissors 2 and the reel sheet 11. When the fishing rod 1 includes the elastic member 31, and the elastic member 31 is formed of, for example, an insulating fiber-reinforced resin material, the electric corrosion of the reel sheet 11 can be prevented.

  The elastic member 31 is fixed to the inner peripheral surface 23a of the mounting hole 23 by, for example, an adhesive. Note that the method of fixing the elastic member 31 to the mounting hole 23 is not limited to adhesion. For example, a double-sided adhesive tape may be used, or an internal thread is formed on the inner peripheral surface 23a of the mounting hole 23 and the outer peripheral surface of the elastic member 31 is used. A male screw may be formed on 31 b and the elastic member 31 may be screwed into the mounting hole 23.

  As shown in FIG. 3, the opening end 24 of the mounting hole 23 is provided with a large-diameter portion 35 that continues to the opening 23c. The large-diameter portion 35 extends over the entire circumference of the inner peripheral surface 23 a along the circumferential direction of the mounting hole 23, and is formed so as to be coaxially continuous along the axial direction of the mounting hole 23.

  The large-diameter portion 35 has an inner diameter larger than that of the other region of the mounting hole 23 (that is, a region outside the large-diameter portion 35). That is, the inner peripheral surface 23 a of the mounting hole 23 includes a first inner peripheral surface 23 aa formed in the large diameter portion 35 and a second inner peripheral surface 23 ab formed in a region outside the large diameter portion 35. . The first inner peripheral surface 23aa is formed on the outer side in the radial direction as compared with the second inner peripheral surface 23ab. The second inner peripheral surface 23ab is in close contact with the outer peripheral surface 31b of the elastic member 31, for example. The first inner peripheral surface 23aa is spaced from the outer peripheral surface 31b of the elastic member 31, and is separated from the outer peripheral surface 31b.

  As shown in FIG. 3, an example of the first inner peripheral surface 23aa is parallel to the axis P of the mounting hole 23, for example. That is, the depth d of the large-diameter portion 35 (that is, the inner diameter difference between the first inner peripheral surface 23aa and the second inner peripheral surface 23ab) is constant over the entire length of the large-diameter portion 35. The shape of the large-diameter portion 35 is not limited to the above. For example, the large-diameter portion 35 may have a tapered surface in which the inner diameter of the first inner peripheral surface 23aa decreases as it proceeds from the opening end 24 toward the bottom end 25. Good.

  The first inner peripheral surface 23aa is open to the end surface 37 of the attachment portion 21. A portion where the first inner peripheral surface 23aa and the end surface 37 of the attachment portion 21 intersect with each other is an edge sharpened at a substantially right angle. This edge defines an opening 23 c of the mounting hole 23.

As shown in FIG. 3, a step 38 is formed at the boundary between the first inner peripheral surface 23aa and the second inner peripheral surface 23ab. The step 38 is along the radial direction of the mounting hole 23 and connects the edge of the first inner peripheral surface 23aa to the edge of the second inner peripheral surface 23ab. The inner edge 38a along the radial direction of the step 38 is chamfered with R or C, for example. When the edge 38a of the step 38 is chamfered, stress can be prevented from concentrating on the edge 38a during elastic deformation of the elastic member 31 described later, and damage to the fishing rod 1 can be avoided.
The step 38 is not necessarily a necessary component, and the first inner peripheral surface 23aa having the tapered surface as described above may be continuous with the second inner peripheral surface 23ab without providing a step.

An example of the large-diameter portion 35 has a total length of about 5 mm along the axial direction of the first inner peripheral surface 23aa. In addition, the suitable range of the full length of 1st inner peripheral surface 23aa is 3 mm-about half of the combined length, for example. If the total length of the first inner peripheral surface 23aa is within the above range, the buttock portion 22 can be stably fixed to the mounting hole 23 without wobbling. Here, the “matching length” is the distance from the opening 23 c of the mounting hole 23 to the end surface 41 of the buttock portion 22 along the axial direction of the mounting hole 23, that is, the tightening between the heel 2 and the elastic member 31. It is a generation.
Further, the depth d of the large diameter portion 35 is about 0.05 mm on the basis of the radius. In addition, the suitable range of the depth d of the large diameter part 35 is 0.02 mm-5 mm, for example.

  As shown in FIG. 3, the fishing rod 1 has a diameter expansion allowable region 51 that allows the elastic member 31 to expand and deform. That is, the fishing rod 1 includes the large-diameter portion 35 so that the inner peripheral surface 23aa of the mounting hole 23 and the outer peripheral surface 31b of the elastic member 31 are between the open end 24 of the mounting hole 23 and the elastic member 31. It has a diameter expansion allowable region 51 which is separated from each other. The diameter expansion allowable region 51 according to the present embodiment is formed by the first inner peripheral surface 23aa of the large diameter portion 35, the step 38, and the outer peripheral surface 31b of the elastic member 31.

  The diameter expansion allowable region 51 may be a gap, for example. As shown in FIGS. 3 and 4, a flexible member 52 is provided in the diameter expansion allowable region 51 according to the present embodiment. Note that the flexible member 52 may be provided over the entire diameter expansion allowable region 51 or may be provided in a part of the diameter expansion allowable region 51. The flexible member 52 disposed in the diameter expansion allowable region 51 is interposed between the first inner peripheral surface 23aa of the large diameter portion 35 and the outer peripheral surface 31b of the elastic member 31.

  The flexible member 52 is made of a material that is softer than the reel sheet 11 and softer than the elastic member 31. A suitable example of the flexible member 52 has elasticity. An example of the material of the flexible member 52 is, for example, rubber, EVA, cork, elastomer, or synthetic resin. The material of the flexible member 52 is not limited to the above example, and various materials can be selectively used as appropriate.

  An example of the flexible member 52 is a tape member made of synthetic resin. The flexible member 52 is provided by, for example, winding a tape around the outer peripheral surface 31 b of the elastic member 31, applying an adhesive on the surface of the wound tape, and pushing the tape into the mounting hole 23 together with the elastic member 31. As the flexible member 52, a molded product formed in a ring shape may be directly attached along the first inner peripheral surface 23aa of the mounting hole 23, or a mold is attached to the inner peripheral surface 23a of the mounting hole 23. It may be formed by a technique such as molding or filling.

  The heel part 22 of the heel 2 is an end of the heel 2 attached to the reel sheet 11. As shown in FIG. 3, for example, a butt plug 55 is provided on the inner side of the end portion of the buttock portion 22 formed in a hollow cylindrical shape. The bottom plug 55 is made of, for example, rubber, elastomer, EVA, cork, synthetic resin, or metal material. A detailed example of the synthetic resin is ABS, nylon, or POM. However, the material of the bottom plug 55 is not limited to the above example. The butt plug 55 is fixed to the inner peripheral surface of the buttock part 22 with an adhesive, for example, and closes the opening of the buttock part 22. By providing the butt plug 55, the strength of the buttock portion 22 is ensured and the buttock portion 22 is protected.

  The bottom plug 55 is formed with a through hole 55a as an air vent hole, for example. The through-hole 55a penetrates the bottom plug 55 and communicates the inside of the collar 2 with the outside. When the buttock 22 is inserted into the mounting hole 23, the air inside the mounting hole 23 is released from the inside of the mounting hole 23 through the through hole 55a. The through hole 55a does not need to be provided at the center of the bottom plug 55, and may be formed in any region. Further, the through hole 55a as an air vent hole is not limited to the one provided in the bottom plug 55, but may be provided on the reel sheet 11 side, for example, when the flange 2 is formed in a solid shape.

  As shown in FIG. 3, when the buttock 22 is inserted inside the elastic member 31, a gap S is formed between the end surface 41 of the buttock 22 and the bottom wall 26 of the mounting hole 23. A mounting hole 23 is formed. If the gap S is provided, it is possible to allow variation in the alignment length of the ridges 2.

  An example of the ridge 2 includes a reinforcing layer whose fiber direction is inclined, for example, by ± 45 ° with respect to the axial direction in the outermost layer. When the heel 2 is provided with such a reinforcing layer, the shear deformation of the heel 2 along the radial direction can be suppressed, and damage to the heel 2 can be prevented. Further, when the reed 2 is provided with such a reinforcing layer, the reed 2 is more difficult to be removed from the reel sheet 11.

Next, an example of the shape of the buttock part 22 and the elastic member 31 will be described in detail. Note that this example does not specify the applicable range of the present invention.
4 and 5 are enlarged views of the taper shape of the buttock portion 22 and the elastic member 31 for explanation. FIG. 4 shows the attachment portion 21 in a state where the collar 2 is not attached. FIG. 5 shows the attachment portion 21 in a state where the flange 2 is attached.

  As shown in FIG. 5, the outer diameter of the end surface 41 of the buttock portion 22 is formed smaller than the inner diameter of the opening 42 of the elastic member 31 and can be inserted into the opening 42. A part of the buttock part 22 has a first outer peripheral surface 22ba that is a tapered surface in which the outer diameter of the heel 2 increases as it moves away from the end surface 41 along the axial direction of the buttock part 22.

  The first outer peripheral surface 22ba is provided from a region separated from the end surface 41 by a predetermined distance along the axial direction of the flange 2, for example. The first outer peripheral surface 22ba has a taper ratio obtained by dividing the outer diameter difference by the axial distance, for example, in a range of 1/1000 to 3/1000. In this embodiment, this taper rate is set to 2/1000. As shown in FIG. 5, the first outer peripheral surface 22 ba includes a portion whose outer diameter is larger than the inner diameter of the opening 42 of the elastic member 31.

  The buttock part 22 according to the present embodiment has a second outer peripheral surface 22bb having a different inclination from the first outer peripheral surface 22ba between the end surface 41 and the first outer peripheral surface 22ba. The second outer peripheral surface 22bb is continuous with the first outer peripheral surface 22ba and has a smaller inclination than the first outer peripheral surface 22ba. The second outer peripheral surface 22bb is formed, for example, as a so-called straight surface having zero inclination, or a tapered surface having a taper rate smaller than that of the first outer peripheral surface 22ba and inclined in the same direction as the first outer peripheral surface 22ba. . The outer diameter of the second outer peripheral surface 22bb is smaller than the inner diameter of the opening 42 of the elastic member 31.

  On the other hand, the inner peripheral surface 31a of the elastic member 31 has, for example, a tapered surface with a constant inclination over the entire axial length. The inner peripheral surface 31a of the elastic member 31 has a taper surface whose inner diameter is enlarged as it proceeds from the bottom end 25 toward the opening end 24, that is, the same direction as the first outer peripheral surface 22ba of the buttock portion 22. And has a tapered surface inclined. The inner peripheral surface 31a of the elastic member 31 is smaller in inclination than the first outer peripheral surface 22ba of the buttock portion 22 and larger in inclination than the second outer peripheral surface 22bb. Further, the inner peripheral surface 31 a of the elastic member 31 includes a portion whose inner diameter is smaller than the outer diameter of the end surface 41 of the buttock portion 22.

  As shown in FIG. 5, according to the buttock portion 22 and the elastic member 31 according to the present embodiment, the first outer peripheral surface 22ba and the second outer peripheral surface 22bb are in contact with the inner peripheral surface 31a of the elastic member 31, respectively. Further, the boundary portion 22bc between the first outer peripheral surface 22ba and the second outer peripheral surface 22bb is separated from the inner peripheral surface 31a of the elastic member 31, and a gap k is formed between the inner peripheral surface 31a.

  When the buttock 22 formed in this way is inserted into the mounting hole 23 by a predetermined distance, a part of the first outer peripheral surface 22ba of the buttock 22 contacts the opening 42 of the elastic member 31. When the buttock portion 22 is further inserted into the mounting hole 23 from a state in which the first outer peripheral surface 22ba is in contact with the opening 42 of the elastic member 31, the second outer peripheral surface 22bb becomes the inner peripheral surface of the elastic member 31. While fitting to 31a, the first outer peripheral surface 22ba elastically deforms the elastic member 31 in the diameter increasing direction at the opening end 24.

  More specifically, as the flange 2 is inserted into the mounting hole 23, the first outer peripheral surface 22ba having a tapered surface presses a part of the inner peripheral surface 31a of the elastic member 31 toward the diameter increasing direction. Thereby, the elastic member 31 is elastically deformed so as to increase in diameter toward the first inner peripheral surface 23aa of the mounting hole 23.

  Here, on the outer side of the elastic member 31 along the radial direction, a diameter expansion allowable region 51 in which a flexible member 52 softer than the elastic member 31 is disposed is provided. Accordingly, as shown in FIG. 5, the region of the pressed elastic member 31 is elastically deformed in the diameter expansion direction toward the diameter expansion allowable region 51, compresses the flexible member 52, and enters the diameter expansion allowable region 51. . That is, the outer diameter of the elastic member 31 is larger than the inner diameter of the second inner peripheral surface 23ab, which is a region outside the large-diameter portion 35, in the diameter expansion allowable region 51.

  The region of the elastic member 31 elastically deformed in the diameter expansion direction tries to return to the original shape by the elastic force, and tightens the buttock portion 22 toward the diameter reduction direction. Further, in the present embodiment, the flexible member 52 compressed by the diameter expansion deformation of the elastic member 31 applies a force for tightening the buttock portion 22 in the direction of the diameter reduction. Thereby, the region 61 of the elastic member 31 facing the vicinity of the opening 42 of the elastic member 31 is fitted to the inner peripheral surface 31 a of the elastic member 31.

  Further, a region 62 in the vicinity of the end surface 41 of the buttock portion 22 is fitted to the inner peripheral surface 31 a of the elastic member 31. Thereby, both ends of the portion inserted into the mounting hole 23 in the flange 2 are fitted into the inner peripheral surface 31 a, and the flange 2 is fitted and fixed inside the elastic member 31. Thereby, the collar 2 is joined to the reel sheet 11.

  Further, in the buttock portion 22 of this embodiment, a boundary portion 22bc between the first outer peripheral surface 22ba and the second outer peripheral surface 22bb forms a gap k between the inner peripheral surface 31a of the elastic member 31. As the butt portion 22 is inserted toward the inner side of the mounting hole 23, a part of the air in the gap k is expelled, and the two regions 61 and 62 are airtight on the inner peripheral surface 31 a of the elastic member 31. In close contact. Thereby, a suction force based on a sealed state acts between the outer peripheral surface 22 b of the flange 2 and the inner peripheral surface 23 a of the mounting hole 23, and the flange 2 is firmly fixed to the mounting hole 23.

  According to the fishing rod 1 having such a configuration, the rod bottom portion 22 can be firmly fixed to the mounting hole 23 of the reel sheet 11. That is, when the diameter expansion allowable region 51 is provided between the mounting hole 23 and the elastic member 31 and the buttock portion 22 inserted into the elastic member 31 elastically deforms the elastic member 31 in the diameter expansion direction, the diameter expansion is performed. The elastic member 31 that has been elastically deformed in the direction faces the direction of diameter reduction and tightens the buttock portion 22. When a force for tightening the heel portion 22 is applied, the engagement force between the heel 2 and the reel sheet 11 is much larger than that due to frictional resistance, and the heel 2 is firmly fixed to the reel sheet 11. Can do.

  In particular, since the reel sheet 11 made of metal has high rigidity, for example, when the inner peripheral surface 23a of the mounting hole 23 is in close contact with the elastic member 31 without including the diameter expansion allowable region 51, the elastic member 31 is in the radial direction. Can't spread outward. Therefore, the elastic member 31 does not apply a large tightening force to the buttock portion 22, and the engagement force between the elastic member 31 and the buttock portion 22 does not become large. On the other hand, according to the reel sheet 11 provided with the diameter expansion allowance region 51, even if the reel sheet 11 is formed of metal, deformation of the elastic member 31 can be permitted.

  When the outer diameter of the elastically deformed portion of the elastic member 31 becomes larger than the inner diameter of the second inner peripheral surface 23ab of the mounting hole 23, the elastic member 31 that is elastically deformed so much tightens the buttock portion 22 tightly. Thereby, the collar 2 can be firmly fixed to the reel sheet 11.

  If the opening end portion 24 of the mounting hole 23 is provided with the diameter expansion allowance region 51, the elastic member 31 and the buttock butt portion 22 at the opening end portion 24 when the heel 2 is inserted into the mounting hole 23. An engagement force is generated between the two. It is preferable that an engagement force is generated at the open end 24 because the fixing of the flange 2 is stable.

  If the flexible member 52 is made of a material softer than the elastic member 31, the flexible member 52 does not hinder the elastic deformation of the elastic member 31. Further, when the flexible member 52 has elasticity, the flexible member 52 also exerts a tightening force on the butt end portion 22 in addition to the elastic member 31, so that the heel 2 can be more firmly fixed to the reel sheet 11. .

  If the buttock 22 has a tapered surface that presses the inner peripheral surface 31a of the elastic member 31 in the diameter increasing direction, the elastic member 31 is naturally expanded in the process of inserting the buttock 22 into the mounting hole 23. A force for elastic deformation can be applied. This contributes to improving the usability of the fishing rod 1.

  The buttock portion 22 has a second outer peripheral surface 22bb having a smaller inclination than the first outer peripheral surface 22ba, the inner peripheral surface 31a of the elastic member 31 is smaller in inclination than the first outer peripheral surface 22ba, and If the outer peripheral surface 22bb has a taper surface having a larger inclination than the outer peripheral surface 22bb, the buttock portion 22 is fitted in the mounting hole 23 in the vicinity of the end surface 41 in addition to the opening end portion 24. Thus, when both ends of the portion inserted into the mounting hole 23 in the collar 2 are fitted to the inner peripheral surface 31a, the fixation of the collar 2 to the reel sheet 11 is very stable.

  Furthermore, the fishing rod 1 having such a configuration is advantageous for preventing damage to the heel portion 22. That is, the buttock portion 22 is attached and detached from the mounting hole 23 along the elastic member 31 that is softer than the reel sheet 11 without directly rubbing against the inner peripheral surface 23a of the mounting hole 23. It is hard to be damaged, and it is hard to become thin by wear.

  Further, when the collar 2 is fitted and held by such an elastic member 31, other fixing parts for fixing the collar 2 can be omitted. This contributes to cost reduction and weight reduction of the fishing rod 1.

  It is advantageous in the following points that the elastic member 31 is not provided to be fixed to the outer peripheral surface 22 b of the buttocks 22 but is fixed to the inner peripheral surface 23 a of the mounting hole 23. For example, the elastic member 31 such as a glass pipe or a carbon pipe can be easily sized when compared to the outer diameter. This is because the inner peripheral surface 31a of the elastic member 31 formed of the material as described above can be finished with high accuracy by, for example, a mandrel method.
