Abstract

PURPOSE: To improve productivity by forming a ball bearing support section on one side from a synthetic resin, providing the support section with a plurality of grooves and inserting a pawl spring in the grooves to support the ball bearing.
CONSTITUTION: A support section 8a for a ball bearing 6 is formed from a synthetic resin 8, a plurality of gooves X are formed in the support section to extend over the outer periphery of the ball bearing, and a pawl spring is inserted in the grooves X to support a ball bearing 6 with inserted pawl portions 13a. The pawl portions 13a of the pawl spring 13 are smaller than the outer diameter dimension of the ball bearing in the free state and adapted to be deformed by ε, and the outer periphery of the ball bearing is supported and secured by the allowance ε. Thus, it is possible to prevent the problem of idling of the ball bearing outer ring stemming from reduction of the size precision due to the molding system and increase of the fitting size due to temperature changes and thus improve the productivity
