[Prior art]

 Conventionally, as a centrifugal brake configured as described above, there is a centrifugal brake disclosed in Japanese Patent Publication No. 30-8116. In this conventional example, with respect to a shaft body that is orthogonal to a spool shaft that integrally rotates with a spool, The collar (contact piece) is slidably fitted on the reel body, and the cylindrical braking member is provided on the reel body side. When the spool rotates, the centrifugal force causes the collar to come into contact with the inner circumference of the braking member, and the braking force is applied to the spool. Is configured to operate.

[0003]

[Problems to be solved by the device]

 At present, the centrifugal brake provided on the bait casting reel is basically the same as the structure of the conventional example described above. The collar is made of resin and the braking member is made of metal. There is also a model with adjustable braking force by changing the collar. Here, considering the assembly of the reel, in the case of a reel having a brake of a conventional structure, a collar is provided on a shaft body that rotates integrally with a spool shaft, and then the relative movement of the spool and the braking member in the proximal direction causes The procedure is to arrange the braking member at the outer peripheral position. However, in this type of brake, since the collar is formed to be relatively small, the outer end position of the shaft is close to the inner circumference of the braking member. In this case, when the braking member or the spool is moved along the axis of the spool shaft, the assembly may be hindered by the contact between the shaft body and the braking member or the contact between the collar and the braking member. is there.

Further, in the state where the collar projects from the end of the shaft body at the time of this assembly, even if the relative position between the side provided with the collar and the side provided with the braking member is set to an appropriate position, the braking member, Alternatively, it is impossible to send the spool to a predetermined position, and conventionally, after pushing the collar with a fingertip, each of them is sent to a predetermined position. In order to enable color replacement, the side case of the reel unit is configured to be separable, the case has the braking member, and the reel unit has a spool and a color. For the reel as well, for the same reason as described above, the protrusion of the collar may make it difficult to close the case or insert the spool, and there is room for improvement. It is an object of the present invention to provide a centrifugal brake for a fishing reel that can be easily assembled by arranging the contact piece and the braking member at predetermined positions with easy operation even when the contact piece and the braking member are in contact with each other. There is a point in configuring.

The action and effect are as follows. Is the street.

[0006]

[Action]

 If the above features are configured, for example, as shown in FIGS. 1 and 2, when the braking member 38 is moved to the side of the spool 3, the protrusion of the contact piece 37 brings the end portion of the braking member 38 into contact. Even if there is, by moving the braking member 38 along the axis X of the spool shaft 19 while maintaining this relative position, the contact piece 37 comes into contact with the inclined surface T of the braking member 38, and the contact state with the movement. Is guided to the inner peripheral side of the braking member 38 and is fed to the inner peripheral surface 38S of the braking member 38. Further, there is a slight discrepancy between the positions of the contact piece 37 and the like and the braking member 38. For example, even if the shaft body 36 supporting the contact piece 37 and the braking member 38 are in contact with each other, this relative position is maintained. By moving the braking member 38 along the axis X of the spool shaft 19, the end of the shaft body 36 comes into contact with the inclined surface T of the braking member 38 to guide the braking member 38 to an appropriate position. Will be things. In other words, in the present invention, the inclined surface T is formed at the end of the braking member 38, which is merely a modification of the shape, so that there is a slight discrepancy in the relative position and relative attitude of the contact piece 37 side and the braking member 38 side. However, it is possible to assemble the brake without pushing the contact piece 37 inward or accurately setting the relative position.

[0007]

[Effect of device]

 Therefore, even if the contact piece and the braking member are in contact with each other, the centrifugal brake of the fishing reel is configured so that the contact piece and the braking member can be easily assembled by arranging the contact piece and the braking member at predetermined positions. It was. In particular, when a collar that fits over the shaft is used as the contact piece, the amount of protrusion of this collar from the shaft is regulated by a stopper, and the maximum diameter of the inclined surface is set larger than the outer end of the collar in this regulated state. In addition, the effect that it is possible to assemble without any special trouble such as pushing in the collar is required. Further, when the present invention is applied to a reel in which the side portions can be opened and closed and the brakes can be released, the side portions can be closed or the spool can be inserted easily and quickly.
