Abstract
A slidable washer (30) has a cylindrical part and a plane part joined thereto. The cylindrical part is placed between an inner circumferential face of a wheel gear (24) and an outer circumferential face of a boss part (23) of a gear housing (22) in order to reduce the frictional force caused during sliding movement therebetween. Further, the plane part joined to the cylindrical part is placed between a side (24b) of the wheel gear (24) and a base (22a) of the gear housing (22) so that the sliding frictional force therebetween is reduced and the cylindrical part of the slidable washer (30) is prevented from inclining toward the axial direction of the boss part (23).
