  • 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.

  • Patent number: 10701917
    Abstract: A dual-bearing reel is described. A clutch mechanism transmits and interrupts the rotational force of the reel handle to the reel spool. A clutch-operating member is movably supported by the reel body between a first position and a second position, and is biased toward the first position. A clutch control mechanism includes a clutch cam that rotates only in one direction each time the clutch-operating member moves from the first to the second position. The clutch control mechanism alternately switches the clutch mechanism to the transmitting state and the interrupting state by rotation of the clutch cam. A clutch return mechanism returns the clutch to the transmitting state by rotation of the handle when the clutch mechanism is in the interrupting state. A regulating member regulates operation of the clutch return mechanism when the clutch mechanism is in the interrupting state by movement of the clutch-operating member.

  • Patent number: 10694727
    Abstract: A clutch operation unit of a dual-bearing reel is attached to a clutch lever extending in a left-right direction parallel to a rotational axis direction of a spool and for moving in an up-down direction with respect to the spool. The clutch operation unit has a first member that is to be operated by a user, and a second member that is combined with the first member to sandwich the clutch lever therebetween in the up-down direction.

  • Patent number: 10028495
    Abstract: A dual-bearing reel includes a reel unit, a spool and an intervening member. The reel unit includes a first reel body and a second reel body. The first reel body includes a first through hole extending in a rotational axis direction. The spool is rotatably disposed between the first reel body and the second reel body. The spool includes a bobbin trunk and a flange. The flange is formed on a first reel body-side end of the bobbin trunk. The intervening member is disposed between the first reel body and the spool. The intervening member is attached to the first reel body. The intervening member includes an annular wall and a second through hole. The annular wall includes an inner peripheral surface opposed to an outer peripheral surface of the flange. The second through hole extends in the rotational axis direction.

  • Patent number: 9591838
    Abstract: A clutch operating member for a dual-bearing reel is disposed at a rear of a reel body of the dual-bearing reel and casts a fishing line in a forward direction. The clutch operating member includes a movable part and a first operating unit. The movable part is movably disposed on the reel body, and is configured to be selectively disposed between a clutch-off position which sets the clutch mechanism in the clutch-off state and a clutch-on position which sets the clutch mechanism in the clutch-on state. The first operating unit has a first end and a second end, is pivotably coupled to the movable part at the first and second ends, and is configured to return the movable part from the clutch-off position to the clutch-on position.
