A spinning reel includes a spool shaft movable in a front-rear direction with respect to a reel body, a spool connected to the spool shaft and configured to have a fishing line wound therearound, a pinion gear supported by the reel body so as to be rotatable, a reciprocating mechanism configured to move the spool shaft in reciprocating fashion in the front-rear direction, and an intermediate gear disposed between the pinion gear and the reciprocating mechanism, the intermediate gear reducing rotation of the pinion gear, and transmitting rotation to the reciprocating mechanism. A value obtained by dividing a stroke distance of the spool shaft by a winding pitch of the fishing line and a module (M) of the intermediate gear is greater than or equal to 60, the module (M) being a diameter of a pitch circle relative to a number of teeth of the intermediate gear.

A gear mounting structure includes a worm shaft, a gear, and an elastic member. The worm shaft includes a shaft body, on the outer surface of which is formed intersecting spiral grooves, and a gear locking portion with a non-circular cross section, on at least a portion of the outer surface of which is formed a curved surface portion and a planar portion. The gear includes a gear body, on the outer surface of which are formed teeth, and to which the handle rotation is transmitted, and a boss portion protruding from the gear body and having an engagement portion engaging the gear locking portion. The elastic member is mounted so as to abut the outer surface of the boss portion of the gear, and at least a portion of the curved surface portion of the gear locking portion.

A spinning reel includes a reel body, a handle, a spool shaft, a spool, a rotor, a reciprocating mechanism, and a clutch mechanism. The handle is rotatably disposed on the reel body. The spool shaft is supported by the reel body. The spool moves in an axial direction of the spool shaft together with the spool shaft. The rotor rotates about the spool by rotation of the handle and winds a fishing line around the spool. The reciprocating mechanism moves the spool shaft back and forth in the axial direction when the rotation of the handle is transmitted thereto. The clutch mechanism switches between a transmitting state to transmit the rotation of the handle to the reciprocating mechanism and a non-transmitting state to terminate the transmission. The reciprocating mechanism enables the spool shaft to move in the axial direction when the clutch mechanism is in the non-transmitting state.

A reciprocating mechanism includes a worm shaft, a slider, a first guide shaft, and an elastic member. The worm shaft includes spiral grooves, and is rotated while the handle is rotated. The slider is reciprocated in the axial direction together with the spool shaft in conjunction with the rotation of the worm shaft. The first guide shaft includes a first supporting portion and a second supporting portion, and guides the reciprocating movement of the slider by an intermediate portion between the first supporting portion and the second supporting portion. The elastic member is mounted on the outer perimeter of at least one of the first supporting portion and the second supporting portion, and supports the first guide shaft in the reel body.

A reciprocating mechanism for a fishing reel includes a first rotating body that rotates around a first axis extending in a direction perpendicular to a spool shaft, a second rotating body that rotates around a second axis disposed at a distance from the first rotating body in the spool shaft direction, and parallel to the first axis, a rotation transmission body bridged between the first rotating body and the second rotating body, and configured to circulate when a handle is rotated, and a movable body having a part engaging the rotation transmission body, the movable body reciprocating in the spool shaft direction together with the spool shaft, when the rotation transmission body is circulated, and when viewed from a direction along the first axis, a virtual straight line that connects the first axis and the second axis is inclined with respect to an axis of the spool shaft.
