Claim 0:
1. A spinning reel, comprising:
a reel body;
a spool shaft movably supported to reciprocate in a front-back direction with respect to the reel body;
a pinion gear disposed outside of the spool shaft in a radial direction and configured to rotate around the spool shaft as the spool shaft reciprocates;
a rotor disposed outside of the pinion gear in the radial direction and configured to rotate integrally with the pinion gear;
a rotor nut disposed between the spool shaft and the rotor in the radial direction, the rotor nut configured to restrict forward movement of the rotor relative to the pinion gear and to rotate integrally with the pinion gear;
a bearing disposed between the spool shaft and the rotor nut in a radial direction and rotatably supporting said rotor nut with respect to said spool shaft; and
a collar member through which the spool shaft passes, the collar member being disposed between the bearing and the spool shaft to support the spool shaft as it reciprocates back-and-forth relative to the bearing,
wherein the collar member is formed by a resin material that has a linear expansion coefficient of 10×10−6 (1/° C.) or more and 50×10−6 (1/° C.) or less, the resin material containing carbon fiber constituting 10-25 weight percent of the resin material.
