Abstract
A retainer member has a retainer portion, a through hole, and non-circular cross section. A bearing section is disposed on an outer periphery of the retainer portion. The through hole has a circular axial cross section and an inner periphery, which is axially penetrated by a non-circular portion of a spool shaft from back to front. The non-circular cross-sectional portion is formed by cutting out a front end of the retainer portion by machining. The non-circular cross-sectional portion has a non-circular axial cross section that engages the non-circular portion of the spool shaft.
Claims20
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.
A spinning reel comprising:
- a handle;
- a rotor;
- a reel unit relatively rotatably supporting the handle and the rotor;
- a spool disposed at a front of the rotor and being configured to have fishing line wound around an outer periphery of the spool, the spool having a spool shaft moving back and forth relative to the reel unit in response to rotation of the handle, the spool shaft having a non circular portion with a non-circular axial cross section on a front end of the spool shaft;
- and
- a spool support structure axially fixed to the spool, the spinning reel spool support structure having
- 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.
