<P>PROBLEM TO BE SOLVED: To provide a lightweight and low-cost spacer for a bearing which can reduce a torque loss during bearing rotation by reducing a sliding resistance with a counter member. <P>SOLUTION: The spacer 4 for the bearing includes a pair of flange parts 14, 16 oppositely arranged making a ring shape, a plurality of column parts 18 which continuously extend over these flange parts and are arranged at predetermined intervals along the circumferential direction, and a plurality of opening pockets 20 constituted at predetermined intervals along the circumferential direction in the part surrounded by the pair of flange parts and the plurality of column parts. In the state incorporated between the bearings, the spacer 4 for the bearing relatively slides with its outer surface touching the bearing constitution being the counter member. By recessing the outer surfaces of both or one of flange parts and column parts in a predetermined range, the area of the outer surface of the spacer touching the bearing constitution as the counter member is made smaller, and the sliding resistance with the counter member is reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
