DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel, and more particularly to an improvement in a fishing reel provided with a drag mechanism for applying a braking force to rotation of a spool around which a fishing line is wound.

[0002]

2. Description of the Related Art Generally, a fishing reel is provided with a drag mechanism which allows a spool to rotate in a fishing line payout direction while applying a braking force to a spool which rotates when the fishing line is fed. In such a drag mechanism, a rotating body such as a spool or a driving gear is rotatably frictionally coupled to a spindle of the reel body, and drag force can be adjusted by changing the friction coupling state. ing. Specifically, a plurality of brake plates are interposed between the rotating body and the support shaft, and a drag force is changed by rotating a drag knob to change the pressure contact state between the braking plate and the rotating body. Can be changed. A lining material is interposed between the friction surfaces (braking surfaces) of the brake plates adjacent to each other, and the braking surfaces of the brake plates are pressed against each other via the lining material.

[0003] In a fishing reel that requires a stable drag performance, it is necessary to improve the rotation performance of the rotating body at the time of feeding the fishing line to obtain a smooth drag action. Therefore, apply grease to the contact surface between the lining material and the brake plate in order to make the operation of the drag smooth without any snagging and to prevent seizure between the lining material and the brake plate on the braking surface. Is commonly practiced. In this case, the grease is usually applied to and retained on the lining material in which the fibers are randomly entangled.However, since the lining material has a weak grease holding power, the friction surface may break off the oil film over a long period of use, causing seizure. May occur. When the oil film breaks in this way, a catching phenomenon called stick-slip occurs, and the operation of the drag becomes unstable, causing problems such as breakage of the thread and breakage of the fish.

In order to solve such a problem, Japanese Patent Application Laid-Open No. Hei 8-147873 discloses a technique for forming a plurality of holes for storing grease in a lining material to prevent oil film shortage. .

[0005]

However, Japanese Patent Application Laid-Open No. Hei 8-1
When a plurality of holes for storing grease are formed in the lining material as in the technology disclosed in Japanese Patent No. 47873, some problems described below occur.

That is, according to this technique, since a hole is formed in a lining material made of a weak material, troubles such as breakage or collapse of the lining material occur, and the durability of the lining material is significantly reduced. In addition, when the drag force is increased and the brake plate and the lining material are pressed against each other with a large force, the volume of the grease reservoir hole, that is, the holding volume of the grease changes slightly, so that the grease protrudes from the lining material,
The protruding grease scatters radially outward due to centrifugal force. Therefore, when used for a long period of time, the oil film on the braking surface runs out. Further, since holes are scattered in the lining material, a pressing force is not uniformly applied to the lining material, and a stick-slip phenomenon occurs.

The present invention has been made in view of the above circumstances, and an object of the present invention is to increase the grease holding force without lowering the strength of the lining material. It is another object of the present invention to provide a fishing reel which can prevent the oil film on the friction surface from being cut and prevent the occurrence of seizure.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a rotating body which is rotated by paying out fishing line, rotatably supported on a support shaft of a reel body, and via a plurality of brake plates. In a fishing reel equipped with a drag mechanism that applies a braking force to the rotating body by frictionally coupling the rotating body to the support shaft in the rotating direction, a lining material is interposed between the braking plates, The surface of the brake plate that comes into contact with the lining material is formed with a concave groove for holding the lubricant.

Specifically, the yoke 87 engaged with the circumferential groove 6a formed in the pinion gear 6 moves along the pinion shaft 5a in conjunction with the ON / OFF operation of the clutch mechanism, thereby causing the pinion to move. The gear 6 can be moved between an engagement position (a state in which the fishing line can be wound; the clutch is ON) and a non-engagement position (a spool free rotation state; the clutch is OFF).

The pinion gear 6 is meshed with a drive gear 7 serving as a rotating body that rotates when the fishing line is paid out. These drive gears 7 are rotatably supported by a handle shaft 8 as a support shaft constituting the winding drive unit 30.

A and 42B extend radially outward in the direction of rotation (the direction indicated by arrow a in the figure). Although not shown, the grooves 75 of the brake plates 41A and 41B that rotate in the opposite direction to the brake plates 42A and 42B during the drag operation are inclined in a direction opposite to the inclination direction of the groove 75 shown in FIG. In addition, the pressing force of the pressing member 43 is applied to the braking plate 41A,
Grooves 75 are provided on brake plates 41A, 41B, 4 so that they act equally on 41B, 42A, 42B and lining material 40.
2A and 42B are formed at an equal distance in the circumferential direction.

Therefore, in such a configuration, the radial groove 75 inclined in the rotation direction can guide the grease deviated radially outward to the radial inside (the direction indicated by the arrow b in the drawing) at the inclined portion. Therefore, an oil film can be uniformly formed on the entire braking surface, and a smooth drag operation can be obtained over a long period of time.
