A fishing reel capable of casting a fishing line in a forward direction includes a reel body, a rotor, a one-way clutch and a case member. The rotor is rotatable relative to the reel body about an axis of rotation and has an internal space. The one-way clutch is configured to transmit power in only one direction. The case member is disposed in the internal space of the rotor and houses the one-way clutch, and has a flange portion projecting in a radially outward direction and a fixing portion disposed behind the flange portion in a position overlapping a part of the flange portion, as viewed from an axial direction, and being fixed to the reel body.

A one-way clutch that allows rotation of a rotation drive shaft in one direction and prevents rotation in the other direction is incorporated in a fishing reel. The one-way clutch has an assembly structure comprising an inner ring, an outer ring, a first holder comprising a holding portion holding a biasing spring for biasing a plurality of rolling members, and a second holder attached to the first holder so as to hold the outer ring in an axial direction. The reel body is provided with a regulation portion that regulates the movement of the one-way clutch in a rotation direction. The first holder and the outer ring are respectively provided with stoppers protruding radially outward. The movement of the one-way clutch in the rotation direction is regulated by the regulation portion and each stopper.

A one-way clutch of the present disclosure comprises an inner ring, an outer ring, and a holder comprising a holding portion holding a biasing spring for biasing a plurality of rolling members. The holder comprises a first holder provided with the holding portion, and a second holder attached to the first holder so as to hold the outer ring in an axial direction. The first holder and the second holder are integrated by an engagement fixing portion provided on a radially inner side of an inner circumferential contour of the outer ring.

A dual-bearing reel includes a reel body, a drive shaft, a roller clutch, and a prevention member. The reel body includes a boss portion. The drive shaft extends through the boss portion and is rotatably supported in the reel body. The roller clutch includes an outer race non-rotatably mounted in the boss portion, an inner race connected to the drive shaft so as to be integrally rotatable, and a rolling element disposed between the outer race and the inner race. The roller clutch prevents rotation of the drive shaft in one direction. The prevention member is mounted on the outer perimeter of the boss portion to prevent radially outward expansion of the boss portion.

A fishing reel of the present invention comprises includes a battery box that accommodates a replaceable battery, a clutch mechanism comprising a clutch operation member that switches a spool between a free rotation state and a fishing line winding state, and a clutch position detection unit that determines whether the clutch mechanism is in an ON state or an OFF state. The clutch position detection unit comprises a magnet held by a holding member that is movable integrally with the clutch operation member, and a clutch detection sensor that detects the magnet, and the clutch detection sensor is accommodated in the battery box.

A level winding device for a fishing reel comprises a tubular body that rotates in conjunction with ON/OFF operation of a clutch mechanism, a worm shaft that is accommodated in the tubular body and rotationally driven by a rotational operation of a handle, a holding body that comprises an engagement pin engaged with a spiral groove of a worm shaft and holds a fishing line insertion portion through which a fishing line is inserted, and two circumferential detent portions (a rib and a recessed portion) provided in the holding body and the tubular body such that two bodies rotate integrally. The two circumferential detent portions are provided on the tubular body at an interval of approximately 180?, and an axial detent portion that suppresses rattling of the holding body in an axial direction of the tubular body is provided at an intermediate position between the two circumferential detent portions.

A dual-bearing reel capable of reeling in and reeling out a fishing line includes a reel body, a spool, a spool shaft, an operating member, and an oscillating mechanism. The spool is rotatably supported by the reel body. The spool shaft supports the spool. The operating member is movably provided on the reel body and moves to perform an adjustment operation on a braking force that acts on the spool. The oscillating mechanism causes the fishing line to oscillate in the axial direction in synchronization with a rotation of the spool.

A dual-bearing reel includes a reel body, a tubular pinion gear, a first bearing, a spool shaft, a spool attached to the spool shaft, and a clutch mechanism. The first bearing member supports an outer perimeter surface of a first end portion of the pinion gear. The spool shaft extends through an interior of the pinion gear and is rotatably supported in the reel body. The clutch mechanism is configured to switch between a clutch on state to connect the pinion gear and the spool shaft, and a clutch off state to release the connection between the pinion gear and the spool shaft. The spool shaft includes a support portion configured to support an inner perimeter surface of a second end portion of the pinion gear in the clutch on state.
