Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a fishing reel having a one-way clutch, and more particularly to a fishing reel having an improved one-way clutch for preventing reverse rotation of a spool.

[0002]

[Prior art]

 Conventional fishing reels are usually provided with a handlebar drive shaft for rotating the spool to prevent the spool from rotating in the fishing line payout direction due to the pulling force of the fish. A one-way clutch is provided as a device.

FIGS. 6 and 7 show a fishing reel equipped with a conventional one-way clutch. The one-way clutch 2 in this fishing reel is first provided with a fixed seat 201. The fixed seat 201 is screwed to an end face 102 of the frame 1 that houses and holds the handle drive shaft 101 so as to surround the handle drive shaft 101 of the fishing reel. In the fixed seat 201, an inner ring 202, a reverse rotation preventing means 203, and an outer ring 204 are sequentially provided from the inside to the outside around the handle driving shaft 101.

The inner ring 202 is externally fitted and fixed to the handle driving shaft 101 as shown in the figure.

The reverse rotation preventing means 203 is provided around the inner ring 202 as a whole. The reverse rotation preventing means 203 mainly includes an annular body 2031 provided around one end of the inner ring 202 and an interlocking plate 2033 located in parallel with the annular body 2031 as shown in the figure. A plurality of protruding pillars 2032 which are locked in a state where their ends are in contact with the interlocking plate 2033 and protrude from one side surface of the annular body 2031 so as to form an annular shape; And a plurality of cylindrical rollers 205 provided in the respective gaps. The annular body 2031 and the interlocking plate 2033 have two substantially annular side surfaces. In addition, the plurality of protruding columns 2032 are combined to form the above-described substantially annular ring. Further, a gap between the protruding columns 2032 is an opening for accommodating the roller 205. Further, the plurality of rollers 205 have their working portions protruding from the inner and outer peripheral surfaces (the inner and outer peripheral surfaces) of the ring body and are rotatably disposed in the opening. Further, the reverse rotation preventing means 203 is further rotated from the outside of the entire reel by a rotation of the control rod 103 between a first position where the reverse rotation can be prevented and a second position where the rotation can be performed in any of two directions. It is configured to be movable.

The outer ring 204 has a non-circular substantially annular shape having an inner peripheral surface having a wedge action, is fitted inside the fixed seat 201, and is provided with the substantially annular reverse rotation preventing means 203. It is provided around.

Further, in the conventional one-way clutch 2, as shown in FIG. 7, one end of each of the plurality of projecting pillars 2032 is provided in order to always hold the reverse rotation preventing means 203 at the first position. Is fixed to the fixed seat 201, and a torsion spring 206 is attached so that the other end thereof abuts the roller 205 on one side thereof.

In the reel provided with the one-way clutch 2, during normal use (first position), as shown in FIG. The handle drive shaft 101 and the inner ring 202 are not reversible due to the wedge action of the inner peripheral surface of the outer ring 204, which is limited between the non-circular inner peripheral surface of the outer ring 204 and the non-circular inner peripheral surface of the outer ring 204. Only the directional rotation is possible.

When a force is applied from the outside via the control rod 103 and the reverse rotation preventing means 203 is moved to the second position, the wedge action on the inner peripheral surface of the outer ring 204 is released. By doing so, the roller 205 does not contact the inner ring 202, and the handle drive shaft 101 and the inner ring 202 can be rotated in either forward or reverse direction.

Note that the reverse rotation preventing means 203 is not locked in this state when the handle driving shaft 101 and the inner ring 202 are moved to the second position where they can rotate in any of two directions. In this case, or when the locking is released, the unidirectional rotation, which cannot be reversed immediately, due to the elastic urging force applied to the roller 205 by the plurality of torsion springs 206 attached to the projection 2032 Return to the first position (see FIG. 7). In other words, the plurality of torsion springs 206 can always maintain the one-way clutch 2 in a one-way rotation state where rotation is not possible.

[0011]

[Problems to be solved by the invention]

 However, the conventional one-way clutch 2 needs to be provided with a torsion spring 206 acting as an elastic means for each of the rollers 205. For example, as shown in FIG. Since the spring 206 is used, there is a disadvantage that the configuration is considerably complicated and the assembly is troublesome.

In the conventional one-way clutch 2, after the fixed seat 201 is screwed to the end face 102 of the frame 1, other parts are sequentially mounted on the handle drive shaft 101. Sometimes, once the fixed seat 201 loses the positional relationship such as the degree of concentricity with respect to the handle drive shaft 101, other components to be subsequently mounted also deviate from a predetermined mounting position, and function as the one-way clutch 2. Or it may be in a bad state, causing loud noises.

[0013] Accordingly, the present invention aims to provide a fishing reel equipped with a one-way clutch which has a simple structure and which does not deviate from a specified mounting position at the time of assembly in order to solve the above-mentioned drawbacks. It is an issue.

[0014]
