Patent ID: 8342438

Claim:
A spinning reel spool support structure movably attached to a reel unit to move in a back-and-forth direction relative to the spool to allow a spool to be rotatably attached onto a spool shaft having a non-circular portion with a non-circular axial cross section at least in a front end portion thereof, the spinning reel spool support structure comprising: a bearing section disposed on an inner periphery of the spool, the bearing section supporting the spool to allow the spool to rotate relatively; a retainer member having a retainer portion having an outer periphery, the bearing section being disposed on an outer periphery of the retainer portion, a through hole having a circular axial cross section and an inner periphery, the inner periphery of the through hole being axially penetrated by the non-circular portion of the spool shaft from back to front, and a non-circular cross-sectional portion formed by cutting out a front end of the retainer portion by machining, the non-circular cross-sectional portion having a non-circular axial cross section engaging the non-circular portion of the spool shaft; and a fixation member fixing the retainer member to the spool shaft preventing the retainer member from axially relatively moving.
