  • Patent number: 10588302
    Abstract: A dual-bearing reel includes a reel body, a spool shaft, an operating member, and a cam mechanism. The reel body includes a frame, a cover member disposed on one side of the frame, and a shaft support part fixed inside the cover member and supported by the frame. One end of the spool shaft is supported by the shaft support part. The operating member is integrally movable with the shaft support part in the axial direction and rotatably mounted on the shaft support part to rotate between a first position where the shaft support part is attached to the frame and a second position where the shaft support part is detached from the frame. The cam mechanism moves the shaft support part in the axial direction in accordance with the rotation of the operating member such that the shaft support part is attached to and detached from the frame.

  • Patent number: 10477849
    Abstract: A dual-bearing reel includes a handle, a spool, a spool shaft, a clutch mechanism, a pinion gear, and an elastic member. The spool shaft is connected to the spool to be integrally rotatable and has a first abutting portion. The pinion gear has a second abutting portion to abut the first abutting portion in the axial direction in the inner circumferential portion thereof, and can move in the axial direction between a coupled position, in which the pinion gear is connected to the spool shaft so as to be integrally rotatable, and a decoupled position, in which the connection is disconnected. When the pinion gear is in the coupled position, the elastic member contacts the distal end of the pinion gear and biases the first abutting portion and the second abutting portion in directions away from each other.
