Abstract
A protrusion, which has three stepped recesses inside, is formed on an outer surface of a spool cover at the center which is a confronting member of a spool. A thrust bearing is fixedly set in the bottom of the recess, and a bearing is fitted in the recess. A guide member is fitted in the recess. The guide member and the bearing are prevented from coming off by a spring washer. The guide member has an inserting hole into which a spool shaft is inserted which is slightly larger in diameter than the inside diameter of the bearing. The guide member has a tapered guide surface around the inserting hole to guide the spool shaft to the inserting hole. The guide surface and the inserting hole enables smooth insertion of the spool shaft into the bearing.
