Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a spinning reel for fishing.

[0002]

2. Description of the Related Art Generally, a spinning reel for fishing has a reel body, a leg portion extending from the reel body, and a rod attachment portion formed at an end portion of the leg portion and attached to a fishing rod. . A handle shaft to which a handle is fixed is rotatably supported in the reel body. A drive gear is fixed to the handle shaft, and a tubular drive cylinder shaft (pinion gear) extending in a direction orthogonal to the handle shaft and rotatably supported by the reel unit is attached to the drive gear. It is in mesh. Further, a rotor is integrally attached to the tip end portion of the pinion gear, and a spool shaft extending in a direction orthogonal to the handle shaft penetrates the pinion gear. In this case, the spool shaft is arranged concentrically with the pinion gear, and can be moved back and forth along the direction orthogonal to the handle shaft by the oscillating mechanism. A spool around which fishing line is wound is attached to the tip of the spool shaft.

[0003]

As described above, in the fishing spinning reel, the spool shaft is moved back and forth in the pinion gear through the oscillating mechanism so that the fishing line is parallel to the spool (uniformly). ). In this case, generally, the inner peripheral surface of the pinion gear is entirely in contact with the spool shaft, and the contact surface between the pinion gear and the spool shaft is a sliding contact surface that rotates while sliding in the axial direction.

However, when the inner peripheral surface of the pinion gear is entirely in contact with the spool shaft in this manner, wear of the sliding contact surface progresses due to long-term use. Therefore, the play between the spool shaft and the pinion gear becomes large and it is necessary to replace it.However, when the pinion gear is replaced, the unit price is high,
There is a problem that the maintenance cost increases.

Further, when the pinion gear is replaced, a meshing error occurs between the new pinion gear and the drive gear, so that it is necessary to perform lapping so as to prevent defective rotation.

Such a problem can be solved to some extent by reducing the sliding resistance between the pinion gear and the spool shaft. Therefore, Japanese Utility Model Registration No. 2530523 and Japanese Patent Laid-Open No. 11-206287 disclose a technique of supporting the spool shaft in a pinion gear by a bearing or a collar to reduce the sliding resistance between the two.

However, utility model registration No. 25305
No. 23 and JP-A No. 11-206287, since the bearings or collars are supported inside the pinion gears, the thickness of the pinion gears supporting these bearings and collars is reduced, There is a problem that the strength of the pinion gear decreases.

Further, generally, in the conventional spinning reel, the front side of the spool shaft is supported by the pinion gear, but the spool shaft is not supported on the front side of the pinion gear. Is located at the frontmost position (when the front side of the spool largely protrudes beyond the support portion by the pinion gear), the spool shaft is insufficiently supported, causing rattling. Such a problem is caused by the utility model registration No. 2530523 and JP-A No. 11-206.
It also occurs in the technology disclosed in Japanese Patent No. 287. That is, in these technologies, the spool shaft is supported by the bearing or the collar inside the pinion gear, and the spool shaft is not supported on the front side of the pinion gear. There is a risk of sticking.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to reduce the sliding resistance between the pinion gear and the spool shaft without lowering the strength of the pinion gear. The object of the present invention is to provide a fishing spinning reel capable of sufficiently supporting the spool shaft and suppressing rattling of the spool shaft.

[0010]

In order to solve the above problems, a fishing spinning reel according to the present invention comprises a reel body and a rotor rotatably supported by the reel body.
A drive cylinder shaft that rotates in association with rotation of a handle attached to the reel body and transmits this rotational force to the rotor and extends through the drive cylinder shaft, and interlocks with rotation of the handle. A spool shaft that moves back and forth; and a spool that is supported by the spool shaft and around which fishing line is wound by the rotation of the rotor. The spool shaft does not come into contact with the drive cylinder shaft over substantially its entire length. The support member is supported by a support member, and the support member is retained by a retaining step formed on a nut for fixing the rotor to the drive cylinder shaft, and is supported forward of the drive cylinder shaft. Has a contact support portion that contacts the spool shaft to support the spool shaft, and the contact support portion forms an extension portion that extends toward the front side of the step portion for retaining. Iruko The features.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. In the present invention,
"Front side" and "tip side" mean reel spool (bale)
The "rear side" and the "proximal side" mean the opposite side.

1 and 2 show a first embodiment of the present invention. As shown in these figures, the fishing spinning reel 1 of the present embodiment includes a reel body 1a,
It has a leg portion 1b extending from the reel body 1a, and a rod attaching portion 1c formed at an end of the leg portion 1b and attached to a fishing rod (not shown). A handle shaft 2 to which a handle 5 is fixed is rotatably supported in the reel body 1a. A drive gear 3 is fixed to the handle shaft 2. The drive gear 3 has a tubular shape that extends in a direction orthogonal to the handle shaft 2 and is rotatably supported by a reel body 1a via a bearing 11. A drive cylinder shaft (hereinafter referred to as a pinion gear) 13 is meshed. The rotor 8 including the bail 6 and the fishing line guide portion 15 is integrally attached to the tip end portion of the pinion gear 13 via a nut 42.

A spool shaft 9 extending in a direction orthogonal to the handle shaft 2 passes through the pinion gear 13. In this case, the spool shaft 9 is arranged concentrically with the pinion gear 13 and can be moved back and forth along a direction orthogonal to the handle shaft 2. A spool 10 around which fishing line is wound is attached to the tip of the spool shaft 9.

The drive gear 3 has a pinion gear 1
The oscillating mechanism 19 is engaged via 3.
The oscillating mechanism 19 includes a worm shaft (traverse cam shaft) 19a that meshes with the pinion gear 13 to rotate, and a slider that meshes with a groove of the worm shaft 19a and is immovably attached to the spool shaft 9 in its axial direction. When the handle shaft 2 is rotated by the rotation operation of the handle 5, the spool shaft 9 is reciprocally driven (back and forth) in the axial direction.

In such a configuration, when the handle 5 is rotated to rotate the handle shaft 2, the rotor 8 is rotationally driven via the drive gear 3 and the pinion gear 13, and the pinion gear 13 and the oscillating mechanism 19 are also driven. The spool 10 attached to the spool shaft 9 reciprocates back and forth. Therefore, the fishing line is evenly wound around the spool 10 via the fishing line guide portion 15.

Further, the reel body 1a is provided with a reverse rotation preventing mechanism for preventing reverse rotation of the rotor 8. The reverse rotation preventing mechanism is an annular ring arranged outside the inner ring 21 and an inner ring 20 that is fitted into the pinion gear 13 in a non-rotating manner and is rotatably supported by the reel body 1 a together with the pinion gear 13 via a bearing 12. Holding body 27 and holding body 27
And an outer ring 25 attached to and fixed to the reel body 1a.

The holder 27 holds a plurality of rolling members 27a. Each rolling member 27a can make frictional contact with the outer peripheral surface of the inner ring 20 to roll due to the rotational movement of the inner ring 20, and can also frictionally contact the inner peripheral surface of the outer ring 25. Further, on the inner peripheral surface of the outer ring 25, a free rotation region where each rolling member 27a can freely rotate (roll), and each rolling member 2
7a is formed to form a wedge region that is in frictional contact with the rolling contact member 7a and prevents rotation of each rolling member 27a. In addition, each rolling member 27a
Is constantly urged toward the wedge region by a spring member (not shown) provided on the holder 27. Also,
The holder 27 has a reversible position in which each rolling member 27a is forcibly positioned in the free rotation region against the biasing force of the spring member, and each rolling member 27a has a wedge region and a free rotation region. The inner ring 20 is moved to and from the reverse rotation prevention position where it can move freely
Can be rotated with respect to.

A rotating member 21 that rotates together with the holding body 27 is attached and fixed to the holding body 27. A slit hole 21 a is provided at the end of the rotating member 21.
Further, one end portion 22a of the switching operation shaft 22 for rotating the holding body 27 between the reversible position and the reverse rotation prevention position via the rotating member 21 is engaged with the slit hole 21a. The switching operation shaft 22 extends parallel to the spool shaft 9 and is rotatably supported by the reel unit 1a.
The other end projects outside from the rear end of the reel unit 1a. An operation knob 23 is attached to the other end of the switching operation shaft 22 protruding from the rear end of the reel unit 1a.

In the reverse rotation preventing mechanism having such a configuration, when the holding body 27 is rotated to the reverse rotation preventing position by operating the operation knob 23 in one direction, the rotor 8 is allowed to rotate normally and reversely rotated. Is blocked. That is, when the inner ring 20 rotates forward together with the pinion gear 13 (the rotor 8 rotates forward in the line winding direction) while the holding body 27 is located at the reverse rotation preventing position, the rolling member 27 of the holding body 27.
Since a is located in the free rotation area of the outer ring 25, the outer ring 25 does not prevent the rolling member 27a from rolling due to the rotation of the inner ring 20. Therefore, the inner ring 20, that is, the rotor 8 can continue to rotate normally. However, when the inner ring 20 reversely rotates together with the pinion gear 13 (the rotor 8 rotates in the yarn feeding direction), the rolling member 27a of the holding body 27 is positioned in the wedge region of the outer ring 25, and the inner ring 20 rolls as the inner ring 20 rotates. The rolling of the moving member 27a is blocked by the outer ring 25. Therefore, the inner ring 20, that is, the rotor 8 cannot rotate in the reverse direction.

On the other hand, when the holding body 27 is rotated to the reverse position by operating the operation knob 23 in the other direction, both the forward rotation and the reverse rotation of the rotor 8 are allowed. That is, when the holding body 27 is positioned at the reversible position, the rolling member 27 a of the holding body 27 is forcibly positioned and held in the free rotation region of the outer ring 25, so that the inner ring 20 is normally moved together with the pinion gear 13. Even if the inner ring 20 is rotated in the reverse direction together with the rotation of the pinion gear 13, the rolling of the rolling member 27a accompanying the rotation of the inner ring 20 is not blocked by the outer ring 25, and the inner ring 20, that is, the rotor 8 is prevented.
Can rotate forward and backward.

As clearly shown in FIG. 2, the spool shaft 9 is supported by a collar member 40 as a support member so as not to come into contact with the pinion gear 13 over substantially the entire length thereof. Specifically, the spool shaft 9 is in contact with the support portion 13a integrally formed at the base end (the end on the right side in the drawing) of the pinion gear 13 and the tip end surface (the end surface on the left side in the drawing) of the pinion gear 13. It is supported by a collar member 40 located on the front side of the pinion gear 13 so as to be movable back and forth,
The pinion gear 13 is not in contact with the pinion gear 13 at any portion other than the support portion 13a.

The collar member 40 is formed (integrated) with a nut 42 for fixing the rotor 8 to the pinion gear 13.
It is supported by a retaining step portion 42a that is retained (movement in the axial direction is regulated; removal from the spool shaft 9 is prevented). Also, the color member 4
Reference numeral 0 has a contact support portion 40a for supporting the spool shaft 9 by contacting the spool shaft 9 on the front side of the pinion gear 13, and the contact support portion 40a is a step portion 42 for preventing slipping off.
The extending portion 40b is formed to extend to the front side of a.

As described above, in the fishing spinning reel 1 according to the present embodiment, the spool shaft 9 does not come into contact with the pinion gear 13 over substantially the entire length thereof. It is supported by the member 40. Therefore, the sliding resistance between the pinion gear 13 and the spool shaft 9 can be reduced while facilitating the machining of the inner peripheral surface of the pinion gear 13.
It is possible to prevent the rotation of the item from becoming heavy due to frictional resistance (sliding resistance). Further, even when the sliding surface wears and the clearance between the sliding surface and the spool shaft 9 increases, only the collar member 40 needs to be replaced, so that the maintenance cost can be reduced. Further, since it is not necessary to replace the pinion gear 14, a good meshing between the pinion gear 13 and the drive gear 3 can be maintained, and a lapping process for proper meshing which is necessary when changing a new pinion gear 13 is eliminated. be able to.

Further, in this embodiment, the collar member 4
Reference numeral 0 has a contact support portion 40a that is in contact with the spool shaft 9 on the front side of the pinion gear 13 to support the spool shaft. The contact support portion 40a has a step portion 42a for preventing slipping off.
The extending portion 40b extending to the front side is formed.
Therefore, since the spool shaft 9 can be supported on the front side of the pinion gear 13, the bending and play of the spool shaft 9 on the front side of the rotor 8 can be effectively suppressed as compared with the related art. Further, the collar member 4 is provided outside the pinion gear 13.
Since there is 0, it is possible to prevent the pinion gear 13 from becoming thin and the strength from decreasing.

Further, in this embodiment, the collar member 4
The step portion 42a for preventing the slipping out of 0 is integrally formed with the nut 42. Therefore, the workability of assembling is improved, and the number of parts can be reduced.

Further, in this embodiment, the spool shaft 9
Is supported not only by the collar member 40 but also by the support portion 13a integrally formed on the rear portion of the pinion gear 13, that is, not only on the front side but also on the rear side, so that they are widely separated from each other. The spool shaft 9 can be sufficiently supported, and the rattling of the spool shaft 9 can be suppressed more effectively.

Further, in the present embodiment, the front extending portion 40b of the collar member 40 has the front end face 42 of the nut 42.
Since it extends to the front side from b, the spool shaft 9 can be supported in a range further apart, and it is possible to reduce rattling of the spool shaft 9 as much as possible.
