Description

The present invention relates to a reel leg fixing device mounted on a fishing rod and capable of mounting various fishing reels.

Conventionally, for example, as disclosed in Patent Document 1, a movable hood and a fixed hood that are separated from each other in the axial direction are provided, and one end of the reel leg is inserted into the fixed hood and the other end of the reel leg is moved in the axial direction. There is known a reel leg fixing device of a type in which a fishing reel is fixed by pressing with a moving hood. In this case, the fixed hood and the movable hood are arranged on a pipe-shaped reel seat attached to the outer periphery of the rod of the fishing rod, and the movable hood is rotated by rotating an operation nut arranged adjacent to the movable hood. Is moved toward and away from the fixed hood, whereby the fishing reel is attached and detached. Usually, the moving hood of the reel leg fixing device (hereinafter, also referred to as a hood portion) is often formed of a metal material, and a pad portion made of synthetic resin is arranged on a portion (the inner surface of the hood portion) with which the reel leg to be inserted abuts. I am trying to set it up.

By the way, recently, it has been required to reduce the weight of the fishing rod, and forming the hood portion with a metal material as described above impedes the reduction in the weight. For this reason, for example, Patent Document 2 discloses molding the hood portion with a synthetic resin.

No. 57-187064 Japanese Patent Laid-Open No. 2009-65868

As described above, the reel leg fixing device causes the moving hood to approach/separate from the fixed hood by rotating the operation nut arranged adjacent to the moving hood. Connects the distal end of the operating nut to the base end of the moving hood, and when the operating nut is rotated in the tightening direction, moves the moving hood to the fixed hood side without rotating, and This is achieved by moving the moving hood away from the fixed hood without rotating the moving hood when the rotating operation is performed in the loosening direction. Then, in this case, the connection between the distal end portion of the operation nut and the proximal end portion of the movable hood generally forms an annular recessed portion at the distal end portion of the operation nut 18, as disclosed in Patent Document 2, It is formed by engaging a bent hook-shaped locking projection, which is provided in an annular shape at the base end of the moving hood, into the recess.

Therefore, in such a connecting portion between the operation nut and the movable hood, a large pressing force acts when the operation nut is tightened to press the reel leg between the movable hood and the fixed hood, and such a pressing force is applied. Even when the operation nut is loosened from the attached state and the moving hood is separated from the fixed hood, a large pulling force acts. Then, such a force causes stress concentration in the connecting portion, particularly in the bent portion of the hook-shaped locking projection of the moving hood, and the moving hood is deformed in the radial direction so as to separate the locking projection from the recess. Try to cause it at the proximal end of.

Therefore, when the moving hood is made of synthetic resin as disclosed in Patent Document 2 described above, it is necessary to secure sufficient strength with this connecting portion, particularly the locking projection of the moving hood. That is, when the moving hood is made of resin for weight reduction, it is essential to secure sufficient strength at such a connecting portion that is likely to cause stress concentration. In some cases, the hood's locking projections may cause breakage. However, if the wall thickness is too large to secure the strength, the weight is increased, which results in the reverse trend of weight reduction. That is, in terms of weight reduction, it is desirable to make the thickness as thin as possible, and efficient and effective weight reduction including securing strength is desired.

The present invention has been made by paying attention to the above-mentioned problems, and effectively and efficiently reduces the thickness and weight of the moving hood while ensuring sufficient strength at the connecting portion between the operation nut and the moving hood. It is an object of the present invention to provide a reel leg fixing device that can be achieved in a desired manner.

In order to achieve the above-mentioned object, the present invention axially moves a cylindrical moving hood having a bulging portion that bulges so as to form an opening capable of accommodating a reel leg of a fishing reel by an operation nut. In the reel leg fixing device, the operating nut and the moving hood are connected by engaging a bent locking portion provided at the end of the moving hood with a recessed portion of the end of the operating nut. In the reel leg fixing device, the moving hood is formed of a fiber-reinforced resin material obtained by impregnating a reinforcing fiber with a synthetic resin, and at least the reinforcing fiber oriented in the axial direction is at least a connecting portion between the operation nut and the moving hood. It is characterized by extending continuously.

According to the reel leg fixing device having the above structure, the moving hood is formed of the fiber reinforced resin material in which the reinforcing fibers are impregnated with the synthetic resin, and therefore the strength is improved as compared with the case where the moving hood is formed of only the synthetic resin. Therefore, it is possible to reduce the thickness while ensuring necessary and sufficient strength. That is, it is possible to effectively and efficiently reduce the thickness and weight of the moving hood while ensuring sufficient strength.

Further, in the above configuration, at least the reinforcing fibers oriented in the axial direction continuously extend at least at the connecting portion between the operation nut and the movable hood, which easily cause stress concentration, so that sufficient strength can be secured at the connecting portion. Damage to parts can be avoided. That is, when the reinforcing fibers oriented in the axial direction are not continuous at the connecting portion, specifically, for example, two or more layers of the reinforcing fibers oriented in the axial direction at the connecting portion (particularly the bent portion) in the radial direction are provided. When the operation nut is tightened or loosened, the layers are separated in the radial direction by the radial outward force based on the above-mentioned inherent pressing force or tensile force acting on the moving hood. Although there is a possibility that they will be broken at their interface along the axial direction, in the above-mentioned configuration according to the present invention, the reinforcing fibers oriented in the axial direction are opposed to the action force peculiar to the connecting portion. Since it extends continuously, it is possible to effectively prevent such breakage. Moreover, since continuous axial fibers also extend in the circumferential direction (radial direction) in the bent portion, continuous reinforcing fibers extend in both the axial direction and the circumferential direction in the entire connecting portion, which results in axial force and twist. A highly rigid connecting portion that is strong against force can be realized.

According to the present invention, there is provided a reel leg fixing device capable of effectively and efficiently reducing the thickness and weight of the moving hood while ensuring sufficient strength at the connecting portion between the operation nut and the moving hood. You will get it.

The fishing rod 1 is configured by splicing a plurality of rods, and in the present embodiment, three rods of a base rod 3, a middle rod 5, and a tip rod 7 are connected in parallel. It has been spliced in. The middle rod 5 may not be provided, or four or more pieces may be joined together. Further, the fishing rod is not particularly limited in its configuration, such as a single rod, a swing-out rod, a centering rod type, in addition to the parallel type.

The base rod 3 is provided with a reel leg fixing device 10 to which a fishing reel 70 is attached, and each rod has a plurality of guide lines for guiding a fishing line fed from the fishing reel at a predetermined interval. A fishing line guide 8 (the tip of the tip rod 7 is a top guide 8a) is attached. The fishing line guide 8 may be configured as a fixed guide that is fixed to the rod or a floating guide that is slidable along the rod.

The main rod 3, the middle rod 5, and the tip rod 7 are made of a fiber-reinforced resin material obtained by impregnating reinforcing fibers (for example, carbon fibers or glass fibers) with a synthetic resin such as epoxy resin, It is configured as a tubular body or a solid body.

The reel leg fixing device 10 provided on the base rod 3 is provided with a fixed hood and a moving hood that moves in the axial direction, and the moving hood is pivoted with the reel leg of the fishing reel inserted in the fixed hood. The fishing reel is configured to be attached and detached by moving in the direction. In this case, the fixed hood may be on the tip side or on the base end side.

Hereinafter, the configuration of the reel leg fixing device 10 of the present embodiment will be specifically described with reference to FIGS. 2 to 4.
The reel leg fixing device 10 includes a reel seat main body (hereinafter, simply referred to as a main body) 11 that is formed in a tubular shape and is externally fitted to the main rod 3. The main body 11 is integrally formed of, for example, a synthetic resin, and has a mounting surface 12 on which the reel legs 71 of the fishing reel 70 are mounted, and a fixed hood 13 disposed on the tip side of the mounting surface 12. And a moving hood 15 arranged on the base end side of the mounting surface 12.

The fixed hood 13 is integrally formed with the main body 11 and includes a hood portion 13A that bulges to accommodate the tip side leg portion 71a of the reel leg 71. The tip side leg portion 71a of the reel leg 71 is a hood portion. It is inserted through the opening 13a of 13A. Note that the hood portion 13A may be formed separately from the main body 11 and integrated with the main body 11, similarly to the hood portion of the moving hood described later.

The movable hood 15 is configured to be movable in the axial direction, and includes a hood portion 15A formed separately from the main body 11. The hood portion 15A of the present embodiment includes a bulging portion 15a bulging so as to accommodate the base end side leg portion 71b of the reel leg 71, and a cylindrical portion 15b integrally formed on the base end side of the bulging portion 15a. Equipped with. That is, the bulging portion 15a has a shape that gradually rises as the circular arc area in the predetermined range on the outer periphery of the cylindrical portion 15b moves to the tip side, and the base end side leg portion 71b of the reel leg 71 has its shape. The bulging portion 15a is inserted through the opening 15c.

The pad member 16 is disposed inside the bulging portion 15a so as to be in pressure contact with the surface of the base end side leg portion 71b of the reel leg 71 to be inserted. The pad member 16 is a portion that is pressed against the surface of the base end side leg portion 71b of the reel leg 71 when the movable hood 15 is moved toward the fixed hood 13, and has a function of firmly fixing the reel leg 71. Have. That is, the pad member 16 is formed in a shape corresponding to the surface of the base end side leg portion 71 b of the reel leg 71, and the protrusion 16 a thereof is fitted into the hole 15 d formed in the bulging portion 15 a of the moving hood 15. By doing so, it is integrated with the inner surface of the bulging portion 15a.

A male screw portion 11a is integrally formed on the base end side of the main body 11, and an operating nut 18 that is moved in the axial direction by a rotating operation is screwed into the male screw portion 11a. The tip of the operation nut 18 is connected to the movable hood 15 (the cylindrical portion 15b of the hood portion 15A). It should be noted that the connection relationship here is that, when the operation nut 18 is rotated in the tightening direction, the movable hood 15 is moved to the fixed hood side without rotating, and the operation nut 18 is rotated in the loosening direction. It is sufficient that the movable hood 15 is moved in a direction away from the fixed hood 13 without rotating.

Specifically, as shown in FIG. 4(a), an annular protrusion 18a is formed on an end edge 18e of the operation nut 18 on the cylindrical portion 15b side, and a locking protrusion 18f protruding outward in the radial direction is formed at the tip of the annular protrusion 18a. By forming the operation nut 18, an annular recess 18g is formed on the outer peripheral surface of the distal end portion of the operation nut 18, and the end portion (base end edge) 15e of the cylindrical portion 15b of the moving hood 15 on the operation nut 18 side is radially inward. The operation nut 18 and the movable hood 15 are connected to each other by forming an annular locking protrusion 15f serving as a locking portion that is bent in a hook shape and protruding to the concave portion 18g. The connecting portion is indicated by reference numeral 20 in FIG.

According to the engagement (connection) relationship between the operation member 18 and the hood portion 15A (cylindrical portion 15b), when the operation nut 18 is rotated in the tightening direction, the operation nut 18 is screwed toward the fixed hood 13 side. At the same time, the movable hood 15 (the cylindrical portion 15b of the hood portion 15A) does not rotate, but is moved toward the fixed hood 13 side by the abutting relationship between the end edges 18e and 15e. That is, the reel leg 71 mounted on the mounting surface 12 is clamped and fixed between the fixed hood 13 and the movable hood 15. Further, when the operation nut 18 is rotated in the direction of loosening, the operation nut 18 is screwed in a direction away from the fixed hood 13, and the moving hood 15 (the cylindrical portion 15b of the hood portion 15A) does not rotate, and the locking projection is retained. It is moved in a direction away from the fixed hood 13 due to the engagement relationship between 15f and the recess 18g. That is, the reel leg 71 placed on the placement surface 12 can be removed from the fixed hood 13 and the movable hood 15.

The movable hood 15 (hood portion 15A) having the above-described configuration is a fiber reinforced resin material obtained by impregnating a reinforced fiber (for example, carbon fiber or glass fiber) with a synthetic resin so that a certain strength can be maintained and weight reduction can be achieved. In this embodiment, the prepreg sheet 40 is formed as shown in FIG. 5A. In this case, in the prepreg sheet 40, the reinforcing fibers are aligned in at least the axial direction (which may include a circumferential direction forming 90° with respect to the axial direction and an inclined direction forming an angle of less than 90° with respect to the axial direction). It is formed into a sheet shape or a sheet shape in which reinforcing fibers are knitted, and is made of a thermoplastic resin (eg, nylon, polypropylene, polyphenyl sulfide, thermoplastic polyurethane) or a thermosetting resin (eg, epoxy resin, phenol resin). , Polyester resin) is impregnated as a matrix resin.

FIG. 5 shows a first example of a method for forming the moving hood 15, and FIG. 5A is a schematic perspective view of a state in which the prepreg sheet 40 forming the moving hood 15 is about to be wound around the mandrel 50, (B) is a side sectional view of the mandrel 50 around which the prepreg sheet 40 is wound. The movable hood 15 is formed by winding the prepreg sheet 40 around the mandrel 50 formed in a predetermined shape, heating the prepreg sheet 40 to cure the synthetic resin, and then decentering the mandrel 50. In FIG. 5 (similar in all the following figures), the reinforcing fibers 42 aligned in the axial direction are schematically shown. Further, the mandrel 50 has a large diameter columnar portion 50a and a small diameter columnar portion 50b so as to have a step 52 for forming the bent portion 44 of the locking projection 15f of the movable hood 15 corresponding to the connecting portion 20.

Here, in the prepreg sheet 40 forming the axial length direction fiber layer, at least the reinforcing fibers 42 oriented in the axial direction are continuously extended at least at the connecting portion 20 between the operation nut 18 and the movable hood 15 ( (For example, the reinforcing fibers 42 oriented in the axial direction are continuously extended over almost the entire length of the moving hood 15 without interruption), and those having a predetermined length are prepared so as to straddle the step 52 of the mandrel 50. Is wound around. In this case, the base end edge 40a of the prepreg sheet 40 may be aligned on the mandrel 50 so as to be longer than the actual base end of the movable hood 14 (the end on the connecting portion 20 side). In that case, after decentering the mandrel, the mandrel is cut to a required length along a cutting line C1 (C2) as shown in FIG.

After the prepreg sheet 40 is wound around the mandrel 50 in this way, the reinforced fiber 42 is bent at the step 52 by winding a tightening tape (not shown) around the outer periphery of the prepreg sheet 40 to tighten the prepreg sheet 40. To form a bent portion 44 as shown in FIG. Then, finally, after heating to cure the synthetic resin, the mandrel 50 is decoreed, and the prepreg sheet 40 is cut if necessary.

In addition, when the prepreg sheet 40 has only the reinforcing fibers extending in the axial direction, the reinforcing fibers may be provided outside or inside the prepreg sheet 40, for example, in the circumferential direction (or less than 90° with respect to the axial direction) as necessary. By winding an unillustrated prepreg sheet aligned in an oblique direction (which may be an oblique direction) in the axial direction, for example, a circumferential fiber layer (an oblique fiber layer, for example, a woven fiber layer may be used). May be provided at least.

FIG. 6 shows a second example of the method for forming the moving hood 15, and FIG. 6A is a schematic perspective view showing a state in which the prepreg sheet forming the moving hood is about to be wound around the mandrel. b) is a perspective view of the mandrel around which the prepreg sheet is wound. In this molding method, a mandrel 50A having a constant diameter over the entire length is used, and as shown in FIG. 6(a), the base end edge 40a of the prepreg sheet 40 substantially corresponds to the length of the locking projection 15f. A plurality of slits 47 having a predetermined length are provided at predetermined intervals (in the present embodiment, slits are provided at equal intervals over the entire circumference of the base end of the moving hood 15 that constitutes the connecting portion 20), and the prepreg sheet 40 6B in a state of being wound around the mandrel 50A, the bending portion is formed by bending the base end portion of the prepreg sheet 40 against the base end surface 50Aa of the mandrel 50A using the slit 47 as shown in FIG. 6B. To form 44 (which may be done, for example, by wrapping the fastening tape as described above). Then, after heating this to cure the synthetic resin, the mandrel 50A is decoreed.

In FIG. 7, at least the portion corresponding to the connecting portion 20 is molded by the molding method of FIG. 5 and cut along the cutting line C1 (see (b) of FIG. 5), or the movement is molded by the molding method of FIG. A perspective view (7(a)) and a side sectional view ((b) of FIG. 7) in which the hood 15 is connected (connected) to the operation nut 18 are shown. This connection state has already been described with reference to FIG. 4B, and will not be described here.

As can be seen from FIG. 7B, in the movable hood 15, at least the reinforcing fibers 42 oriented in the axial direction are provided at least at the connecting portion 20 between the operation nut 18 and the movable hood 15 (for example, over substantially the entire length of the movable hood 15). ) It extends continuously without interruption. In this case, at least the axially oriented reinforcing fiber 42 expands from the tip of the locking projection 15f (the end surface facing the radially inner side at the base end of the moving hood 15) via the bent portion 44 of the locking projection 15f. It continuously extends toward the projecting portion 15a side without interruption.

As described above, according to the reel leg fixing device 10 of the present embodiment, since the moving hood 15 is formed of the fiber reinforced resin material in which the reinforcing fiber is impregnated with the synthetic resin, the moving hood 15 is made of only the synthetic resin. The strength can be improved as compared with the case where it is formed, and therefore, it becomes possible to reduce the thickness while ensuring the necessary and sufficient strength. That is, with respect to the movable hood 15, it is possible to effectively and efficiently reduce the thickness and weight while ensuring sufficient strength.

Further, in the present embodiment, at least the reinforcing fibers 42 oriented in the axial direction continuously extend at least at the connecting portion 20 between the operation nut 18 and the movable hood 15 where stress concentration is likely to occur, so that the connecting portion 20 is sufficient. The strength can be secured, and damage or the like can be avoided at the connecting portion 20. That is, when the reinforcing fibers 42 oriented in the axial direction are not continuous in the connecting portion 20, specifically, for example, the layer of the reinforcing fibers oriented in the axial direction in the connecting portion 20 (particularly the bent portion 44) is in the radial direction. When the operation nut 18 is tightened or loosened, the radial direction outward force based on the inherent pressing force or pulling force acting on the moving hood 15 causes the radial direction to increase in the radial direction. There is a risk that the layers separated by will be broken at the interface along the axial direction, but in the configuration of the present embodiment, the reinforcement directed in the axial direction is resisted against such an action force specific to the connecting portion 20. Since the fibers 42 continuously extend at the connecting portion 20, such breakage can be effectively prevented. Further, in the bent portion 44, the continuous axial fibers also extend in the circumferential direction (radial direction) (see (b) of FIG. 7 ), so that continuous reinforcing fibers are axially and circumferentially formed in the entire connecting portion 20. Thus, it is possible to realize a high-rigidity connecting portion that is strong against axial force and twisting force, since it is extended in both directions (particularly, the tendency is remarkable in the second embodiment of FIG. 8 described later).

FIG. 8 shows a side sectional view of the moving hood 15 of the reel leg fixing device and the operation nut 18 connected thereto according to the second embodiment of the present invention. As illustrated, in the present embodiment, the movable hood 15 is formed by cutting the prepreg sheet 40 along the cutting line C2 of FIG. 5B to form at least a portion corresponding to the connecting portion 20 by the manufacturing method of FIG. Has been done. That is, in the present embodiment, the concave portion 18g′ of the operation nut 18 is formed to be longer in the axial direction than the concave portion 18g of the first embodiment, and correspondingly, the locking of the moving hood 15 that locks in the concave portion 18g′. The projection 15f′ is also formed such that the base end side from the bent portion 44 is elongated in the axial direction. In such a configuration as well, the same operational effects as in the first embodiment can be obtained, and the connected state (locked state) of the connecting portion 20 becomes stronger, and the rigidity of the connecting portion 20 can be further increased.

FIG. 9 shows a side sectional view of the moving hood 15 of the reel leg fixing device and the operation nut 18 connected thereto according to the third embodiment of the present invention. As illustrated, in the present embodiment, the reinforcing member 60 that suppresses the radial deformation of the moving hood 15 at the connecting portion 20 is provided on the outer periphery of the fiber reinforced resin material located at the connecting portion 20. Specifically, a metal ring-shaped member (metal ring) is provided on the outer periphery (on the side of the base end just behind the bent portion 44) of the locking projection 15f′ of the movable hood 15 according to the second embodiment. A reinforcing member 60 is fitted, and the reinforcing member 60 has a function of suppressing the deformation of the prepreg sheet 40 at this portion, particularly, the deformation outward in the radial direction. That is, by disposing the reinforcing member formed of such a ring-shaped member, stress concentration does not occur at the portion of the connecting portion, and the locking projection 15f' is prevented from being detached from the recessed portion 18g'. The reinforcing member 60 may be made of a prepreg sheet having reinforcing fibers oriented in the circumferential direction instead of the metal ring. Even a prepreg sheet having such reinforcing fibers oriented in the circumferential direction can effectively suppress the radial deformation of the prepreg sheet 40.

FIG. 10 shows a side sectional view of the moving hood 15 of the reel leg fixing device according to the fourth embodiment of the present invention and the operation nut 18 connected thereto. As shown in the figure, also in the present embodiment, the reinforcing member 62 that suppresses the radial deformation of the moving hood 15 at the connecting portion 20 is provided on the outer periphery of the fiber reinforced resin material located at the connecting portion 20. Specifically, the reinforcing member 62 formed of a metal ring is provided on the outer periphery of the locking projection 15f of the movable hood 15 according to the first embodiment (on the side of the tip immediately before the bent portion 44 (on the side toward the bulging portion 15a)). The reinforcing member 62 also prevents the prepreg sheet 40 from being deformed radially outward in this portion so that stress concentration does not occur in this portion, and therefore the locking from the recessed portion 18g. The detachment of the protrusion 15f is also prevented. The reinforcing member 62 may be made of a prepreg sheet having reinforcing fibers oriented in the circumferential direction instead of the metal ring.

FIG. 11 shows a side sectional view of the moving hood 15 of the reel leg fixing device and the operation nut 18 connected to the moving hood 15 according to the fifth embodiment of the present invention. As shown in the figure, also in the present embodiment, the reinforcing member 64 that suppresses the outward deformation of the moving hood 15 in the connecting portion 20 in the radial direction is provided on the outer periphery of the fiber reinforced resin material located in the connecting portion 20. Specifically, a reinforcing member 64 made of a metal ring is fitted to the outer periphery of the locking projection 15f of the moving hood 15 according to the first embodiment, more specifically, so as to straddle the bent portion 44. There is. Therefore, the reinforcing member 64 has a cylindrical portion 64a that extends in the axial direction on the tip side of the bent portion 44 and a bent flange 64b that extends radially inward from the bent portion 44. Such a reinforcing member 64 prevents the prepreg sheet 40 from being deformed radially outward and axially outward at this portion so that stress concentration does not occur at this portion, and therefore, the locking projection from the recessed portion 18g. It also prevents disengagement of 15f. The reinforcing member 64 may be formed of a prepreg sheet having carbon fibers oriented in the circumferential direction instead of the metal ring.

FIG. 12 shows a side sectional view of the moving hood 15 of the reel leg fixing device and the operation nut 18 connected to the moving hood 15 according to the sixth embodiment of the present invention. As shown in the figure, in the present embodiment, a reinforcing member 66 that suppresses deformation of the moving hood 15 at the connecting portion 20 to the radial outside is provided on the inner periphery of the fiber reinforced resin material located near the connecting portion 20. It is provided. Specifically, a circumferential fiber having reinforcing fibers oriented in the circumferential direction on the inner circumference of the prepreg sheet 40 on the tip side of the locking projection 15f (bent portion 44) of the moving hood 15 according to the first embodiment. A layer (for example, a prepreg sheet) is laminated (or fitted) as the reinforcing member 66.

FIG. 13 shows an example of a method for molding the moving hood 15 shown in FIG. 12, and FIG. 13( a) shows a circumferential fiber layer (for example, a prepreg sheet) forming the reinforcing member 66 of the moving hood 15. And a schematic perspective view of the Teflon (registered trademark) tape 67 as a spacer about to be wound around the mandrel 50B. FIG. 13B shows the prepreg sheet 40 and the reinforcing member 66 that form the moving hood 15 and the Teflon ( It is a side sectional view of a mandrel 50B on which a registered trademark) tape 67 is wound. The mandrel 50B in this case has a stepped portion for forming a large-diameter columnar portion 50Ba having a tapered shape that corresponds to the bulge 15a of the movable hood 15 and a bent portion 44 of the locking protrusion 15f of the movable hood 15. It has a small-diameter column portion 50Bb extending from the large-diameter column portion 50Ba via 52.

In order to provide the reinforcing member 66 as shown in FIG. 12 on the inner circumference of the prepreg sheet 40 (moving hood 15), for example, as shown in FIG. 13(a), on the outer circumference of the small-diameter columnar portion 50Bb, The reinforcing member 66 is wound so as to abut against the step 52, the Teflon (registered trademark) tape 67 is wound around the base end side of the small-diameter columnar portion 50B adjacent to this, and further, from the outside of these members 66, 67, As described above, the prepreg sheet 40 may be wound around the outer periphery of the mandrel 50B (which may include forming the bent portion 44 by tightening with the above-described tightening tape), and heating/decentering. After the molding, the Teflon (registered trademark) tape 67 is removed from the prepreg sheet 40, whereby an annular concave portion into which the locking projection 18f of the operation nut 18 enters is left on the inner surface of the prepreg sheet 40.

Such a reinforcing member 66 also prevents the prepreg sheet 40 from being deformed radially outward and axially outward at this portion so that stress concentration does not occur at this portion, and therefore, the locking protrusion from the recessed portion 18g. It also prevents disengagement of 15f.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described configuration and can be variously modified.
