  • Patent number: 11659825
    Abstract: A dual-bearing reel includes a reel body, a handle shaft, a handle, a first bearing, and a roller clutch. The handle shaft has a first end portion and a second end portion on a side opposite the first end portion, and is provided on the reel body so as to be rotatable. The handle is connected to the first end portion of the handle shaft. The first bearing rotatably supports the second end portion of the handle shaft. The roller clutch is arranged so as to overlap the first bearing in an axial direction of the handle shaft as seen from a radial direction of the handle shaft and is configured to prohibit rotation of the handle shaft in one direction.

  • Patent number: 11612156
    Abstract: A torque limiting device for a fishing reel for limiting torque between first and second rotating members, the torque limiting device includes an engagement recess, an engagement member and a biasing member. The engagement recess is disposed on an inner circumferential surface of the second rotating member. The engagement member has a head portion that engages the engagement recess and is disposed on the first rotating member so as to be capable of advancing toward or retreating from the second rotating member. The biasing member biases the engagement member toward the second rotating member. The head portion of the engagement member has a straight part at a distal end that extends linearly in a direction of the axis of rotation of the first rotating member.
