[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dual-bearing reel, and more particularly to a structure of a centrifugal brake.

[0002]

2. Description of the Related Art Generally, a dual-bearing reel in which a spool shaft is supported at both ends is widely known. In this dual bearing reel, a centrifugal brake device is provided to brake the rotation of the spool shaft and prevent backlash.

A mechanism capable of adjusting the braking force of this centrifugal brake device has been proposed (Japanese Utility Model Laid-Open No. 3-79665). 3-79
No. 665 describes that the braking surface of a brake drum configured to be able to change its position in the axial direction of the spool shaft is formed to have a tapered or stepwise enlarged diameter, and the distance from the rotation center to the braking surface is changed. Thus, the braking force is adjusted.

[0004]

However, when the braking surface of the brake drum is formed in a tapered shape as described above, the contact surface of the brake shoe also needs to be formed in a tapered shape, and a direction is required at the time of assembly. , And it is difficult to assemble and adjust thereafter. Further, if the braking surface of the brake drum is formed in a step shape, there is a problem that the braking force cannot be finely adjusted.

The present invention has been made in view of the above-described problems, and has as its object to provide a dual-bearing reel that is easy to assemble and that can finely adjust a braking force.

[0006]

SUMMARY OF THE INVENTION The present invention comprises a reel body constituting an outer shell of a reel, a spool shaft having both ends pivotally supported by the reel body, and a spool fixed to the spool shaft. In the dual-bearing reel, the reel body has a projection penetrating through a hole formed in the reel body, and is guided by a boss formed in the reel body while the shaft of the spool shaft is being guided. A slide member is provided so as to be movable in the direction, a brake plate is provided on the slide member, the protrusion is inserted into the reel body, and the tip of the protrusion comes into contact with the slide body to move the slide member. provided a brake adjusting member holes are drilled with a cam surface which, in the spool shaft at least two support rods in different axial position of the spool shaft in the radial direction Above provided, this support rod braking member is provided for braking in contact with the axially movable the braking plate of the support rod, in accordance with the movement of the slide member
The contact area between the braking member and the braking plate changes .

[0007]

When releasing the fishing line, the brake adjusting member is operated in order to brake the rotation of the spool. A slide member provided with a brake plate abutting on the cam surface of the brake adjusting member is moved in the axial direction of the spool shaft according to the cam surface. Due to this movement, the overlapping area between the brake plate and the contact portion of the braking member changes, and the contact area between the brake plate and the braking member changes. Therefore, fine adjustment of the braking force can be performed. That is, when the braking force is to be increased, the brake adjustment member is adjusted so that the contact area between the braking plate provided on the slide member and the braking member of the support rod is increased, and when the braking force is to be reduced, the slide member is adjusted. The brake adjustment member may be adjusted so that the contact area between the brake plate provided in the above and the brake member of the support rod is reduced.

Is provided, and always urges the slide cam 12 to the left in the figure. A lid 15 is attached to the left side of the reel body 1 in the drawing, and a brake adjusting screw 16 is rotatably provided on the lid 15. The brake adjusting screw 16 has an arc-shaped hole 16b having a cam surface 16a formed at a rear end. The projection 12a of the slide cam 12 is inserted into the arc hole 16b, and the tip of the projection 12a is in contact with the cam surface 16a. A squeal claw 17 is fixed inside the lid 15 so that the brake adjusting screw 16 is positioned.

In FIG. 2, the spool shaft 7 is provided with first support rods 18, 18 in the vertical direction in the figure, and each of the first support rods 18, 18 has a brake shoe 1
Reference numerals 9 and 19 are provided so as to be movable in the axial direction of the first support rod 18. Further, second support rods 20, 20 are fixed to the spool shaft 7 in the left-right direction in FIG. 2 and leftward in FIG. 1 of the first support rod 18 in FIG. In FIG. 2, brake shoes 21, 21 are provided on each of the second support rods 20, 20 so as to be movable in the axial direction of the second support rod 20. Here, a stopper portion 20 a is formed at a tip end of the second support rod 20, and the brake shoe 21 is disengaged from the second support rod 20 by engaging with the engagement portion 21 a of the brake shoe 21. Has been prevented. 1, a flange portion 19a is formed in the brake shoe 19, and the flange portion 19a is located in the concave portion 11a of the spool 11. Therefore, the flange portion 19a is locked to the end surface 11b of the concave portion 11a, so that the brake shoe 19
Are stopped from the first support rod 18.

The operation of the dual-bearing reel configured as described above will be described below. To adjust the braking force applied to the rotation of the spool 11, the brake adjustment screw 16 is rotated in FIG. At this time, the rotational position of the brake adjusting screw 16 can be confirmed by counting the number of sounds generated by the engagement between the squeeze claws 17 and the engagement teeth 16c. Further, the rotational position can be finely adjusted, and the adjusted position can be held by the engagement between the squealing claws 17 and the engagement teeth 16c. Brake adjustment screw 16
Is rotated, the position of the cam surface 16a with which the tip of the projection 12a of the slide cam 12 abuts changes. Therefore, the slide cam 12 moves in the left-right direction in the figure while being guided by the boss 5a of the brake plate support member 5. Then, the brake plate 13 provided on the slide cam 12 also moves in the left-right direction in FIG.
The contact area that contacts the brake plate 13 changes. That is, when the braking of the rotational force of the spool 11 is increased,
In order to increase the contact area between the brake plate 13 and the brake shoes 19 and 21, the slide cam 12 is moved to the right in FIG. When it is desired to reduce the braking of the rotational force, the brake plate 13 and the brake shoe 1

2 is moved to the left in FIG. 1 by the above operation.

After fine adjustment to the desired braking force in this manner, a releasing operation is performed to release the fishing line. Thereby, the spool shaft 7 and the spool 11 rotate, and the fishing line is sequentially fed. On the other hand, the rotation of the spool shaft 7 causes the first support rod 18 and the second support rod 20 to also rotate, and the rotation causes the brake shoes 19 and the brake shoes 21 provided on the first support rod 18 and the second support rod 20 to rotate. In order to move in the centrifugal direction by the centrifugal force, it is pressed against the brake plate 13 in FIG. Thereby, the rotation of the spool shaft 7 and, consequently, the rotation of the spool 11 are braked. In addition, it is possible to prevent the spool 11 from rotating more than the amount of fishing line fed when the fishing line is released, and thus to prevent backlash. In FIG. 1, the brake shoe 19 has a flange portion 19 a having an end surface 1 of the spool 11.
The contact with the first support rod 18 prevents the first support rod 18 from coming off. In FIG. 2, the engagement portion 21 a of the brake shoe 21 has a stopper portion 2 of the second support rod 20.
The engagement with Oa prevents the second support rod 20 from coming off.

In the above embodiment, the case where the number of the support rods is two has been described. However, the number of the support rods is not necessarily two, and as shown in FIG. The first support rod 18 and the second support rod 20 may be provided at different positions in the axial direction of the spool shaft 7.

[0014]

According to the present invention, as described above, the braking force applied to the spool can be finely adjusted as desired, and backlash can be effectively prevented. Further, the adjustment operation can be easily performed by operating the brake adjustment member. Furthermore, since the contact surface of the brake shoe is not formed in a tapered shape, it is not necessary to consider the direction at the time of assembling, and it is possible to easily perform an assembling operation.
