Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fishing spinning reel, and more particularly to an improvement in a support structure of a drive cylinder shaft (pinion gear) that is rotatably supported by a reel body.
[0002]
[Prior art]
2. Description of the Related Art Generally, a fishing spinning reel has a reel body, a leg portion extending from the reel body, and a rod attachment portion that is 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 pinion gear serving as a drive cylinder shaft extending in a direction orthogonal to the handle shaft is engaged with the drive gear. A rotor provided with a fishing line guide is integrally attached to the tip of the pinion gear, and a spool shaft extending in a direction perpendicular to the handle shaft passes through the pinion gear. In this case, the spool shaft is arranged concentrically with the pinion gear and can move back and forth along a direction perpendicular to the handle shaft. A spool around which the fishing line is wound is attached to the tip of the spool shaft via the fishing line guide.
[0003]
By the way, the pinion gear is rotatably supported by a front portion of the reel body via a bearing. Further, this bearing for supporting the pinion gear is generally secured to the reel body by a plurality of screws directly or by a plurality of screws via a locking plate.
[0004]
However, in such a configuration in which the bearing is retained and locked using a plurality of screws and locking plates, the tightening force of the screws is likely to be uneven, and the bearing may be tilted or the pinion gear may be loose. . Moreover, since the number of parts increases, it has been pointed out that the assembly work takes time and the workability is poor.
[0005]
Therefore, in order to improve such a problem, the present applicant, as disclosed in the registered utility model No. 3001861, has a plate-shaped retaining member, that is, a bearing having a shaft hole through which the pinion gear penetrates. A structure has been proposed in which the bearing is prevented from coming off and locked by a single member that is integrally pressed from the side.
[0006]
[Problems to be solved by the invention]
Since the support structure disclosed in the registered utility model No. 3001861 can press the bearing uniformly, the support structure and the pinion gear can be prevented from being tilted or loosened.
[0007]
However, since the retaining member is for supporting the bearing, generally, even if dust can be prevented from entering the inside of the reel body, between the pinion gear and the retaining member, and Intrusion of water (seawater, fresh water) between the reel body and the retaining member may not be prevented. In particular, since the retaining member is screwed to the outer peripheral surface of a cylindrical portion formed at the front portion of the reel body, there is a possibility that moisture may be sucked up by a capillary phenomenon and penetrated into the inside, which is improved. is needed.
[0008]
The present invention has been made paying attention to the above circumstances, and the object of the present invention is to prevent the bearing supporting the drive cylinder shaft from coming off and to prevent the entry of water or the like through the retaining portion. The object is to provide a spinning reel for fishing.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a drive cylinder shaft that is rotated in conjunction with a handle and has a spool shaft at a front portion thereof, and is inserted into the front portion of the reel body. A fishing spinning spinning reel comprising a bearing that is rotatably supported and a rotor that is attached to the drive cylinder shaft and has a fishing line guide that winds a fishing line around the spool. A cylindrical support portion that accommodates and holds at least one of the one-way clutch that prevents reverse rotation and the bearing therein, and a shaft hole through which the drive cylinder shaft passes, are screwed to the cylindrical support portion. A stopper member that closes the opening of the cylindrical support portion, presses at least one of the one-way clutch and the bearing evenly into the cylindrical support portion, and is attached around a shaft hole of the stopper member; on the other hand It includes a fixed portion fixed by being sandwiched between the clutch or bearing, and a sealing member having a contact lip portion for contacting to be elastically deformable in the boss portion or the intermediate member rotor mounted on the drive cylinder axis The contact lip portion that contacts the boss portion or the intermediate member of the rotor mounted on the drive cylinder shaft prevents water from entering through the shaft hole of the retaining member.

The drive gear 3 is engaged with an oscillating mechanism (not shown) via a pinion gear 13. The oscillating mechanism includes a worm shaft (traverse cam shaft) that meshes with the pinion gear 13 and rotates, and a slider that meshes with the groove of the worm shaft and is nonmovable in the axial direction with respect to the spool shaft 9. Thus, when the handle shaft 2 is rotated by the rotating operation of the handle 5, the spool shaft 9 is reciprocated (back and forth) along the axial direction.
[0016]
In such a configuration, when the handle shaft 2 is rotated by rotating the handle 5, the spool 10 attached to the spool shaft 9 reciprocates back and forth via the oscillating mechanism, and the drive gear 3 and the pinion The rotor 8 is rotationally driven via the gear 13. Accordingly, the fishing line is evenly wound around the spool 10 via the fishing line guide device.
