Patent ID: 7802744

Claim:
A spinning reel configured to be mounted to a fishing rod and to reel out a fishing line forward, comprising: a reel unit configured to be mounted to the fishing rod, the reel unit including a handle; a spool shaft mounted to the reel unit and arranged to move along an anteroposterior direction; a spool fixedly coupled to a front end portion of the spool shaft and the fishing line being wound around the outer periphery of the spool; a rotor rotatably disposed on the outer periphery of the spool, the rotor being adapted to wind the fishing line around the spool; a master gear rotatably supported by the reel unit, the master gear including a master gear shaft and a gear part, the handle being integrally and rotatably mounted to the master gear shaft, the master gear being disposed on the fishing rod mounting side of the spool shaft, the gear part being disposed on the outer peripheral side of the master gear shaft, the gear part being configured to transmit rotation of the handle to the rotor; a pinion gear disposed on the outer peripheral side of the spool shaft, the pinion gear being integrally and rotatably mounted to the rotor, the pinion gear to which rotation of the master gear is transmitted in conjunction with rotation of the handle; and an oscillation mechanism configured to move the spool back and forth along the spool shaft in conjunction with rotation of the pinion gear, the oscillation mechanism including a worm shaft having a spiral groove on the outer peripheral part thereof, the worm shaft being disposed on the fishing rod mounting side of the master gear shaft substantially parallel to the spool shaft, the worm shaft being configured to rotate in conjunction with rotation of the pinion gear, and a slider having an engaging member and a slider body, the engaging member being engaged with the spiral groove of the worm shaft, the engaging member being mounted on the slider body, the slider body being configured to move back and forth in conjunction with rotation of the worm shaft, the slider body including a first mounting portion to which a rear end of the spool shaft is at least relatively non-rotatably mounted in an axial direction, a second mounting portion to which the engaging member is mounted, and a coupling portion arranged to couple the first mounting portion and the second mounting portion so that the master gear shaft is straddled by the first mounting portion and the second mounting portion when the spool shaft is positioned most forward, the first and second mounting portions being positioned anterior to the master gear shaft when the spool shaft is positioned most forward.
