Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dual-bearing reel for fishing, which brakes a spool shaft.

[0002]

[Prior art]

 From the viewpoint of preventing backlash when releasing fishing line and applying braking force to the spool easily by responding to fish, a device that presses on the end of the spool shaft and brakes the spool has been developed. It has been used conventionally as seen in the -5370 publication. However, because the top surface of the end surface of the spool shaft or the small-diameter portion is concentrated and pressed by a pressing portion such as a washer, and the friction generated when the spool shaft rotates is used, the pressing portion is pressed. The washer and spool shaft end are easily worn and inferior in terms of durability, and seizure, etc. occurs, and a strong spool braking force cannot be applied, making it suitable for a wide variety of tackles and target fish. There was a problem that could not be dealt with.

[Action]

 As shown in FIGS. 2 and 3, a small diameter portion 3e is formed on the spool shaft end portion 3d to provide a friction surface 3f formed of a step portion, and the braking member 4 can be pressed against the friction surface 3f formed of the step portion. Has become. The braking member 4 is formed in a disc shape and is engaged with an inner cylinder 5a integrally formed with the braking knob 5 at a protrusion 5b and a recess 4a. The braking knob 5 is screwed onto the outer circumference of the tubular portion 2a of the reel side plate 2. When the braking knob 5 is rotated in the direction in which the braking force is applied, the braking force of the spool shaft 3 is brought into pressure contact with the friction surface 3f formed by the stepped portion of the spool shaft 3 to apply the braking force. Be released.
