Description

  The present invention relates to an improvement in a fishing reel provided with a braking device that applies a braking force in the rotational direction of a spool around which a fishing line is wound.

Conventionally, a knob for adjusting a braking force applied to a rotating body (spool, interlocking gear, etc.) that is rotated by feeding a fishing line of a fishing reel is screwed on a support shaft that supports the rotating body. Thus, the brake plate that frictionally couples the rotating body to the support shaft is pressed in the axial direction.
The knob is composed of a knob body having an operation portion operated by a finger and a pressing member that presses the brake plate, and the pressing member is disclosed in Patent Document 1 and Patent Document 2 with respect to the knob body. They are integrally attached by means such as elastic deformation locking and retaining plates, screws and the like.
