PURPOSE:To prevent application of radial load onto a roll bearing completely by providing a rolling member through a holding member such that a plurality of rolling members are contacted between a roll bearing to be applied with thrust load, positioning member and bearing stopper. CONSTITUTION:A holder 28 for rolling member 29 is integrated with a tubular section 28a having a margin for fastening with the outercircumferential side face of the outer ring of bearing and a disc section 28b having plural holes with equi-interval for holding the rolling member 29. The holder 28 can be fixed to the outercircumference of the outer ring of angular ball bearings 13a, 13b while fixed in axial direction at such position for restricting the rolling member 29 with the end face of the outer ring of shaft and the holes in the disc section of holder 28. Consequently, the angular ball bearings 13a, 13b for receiving the thrust load of rotor can be completely protected from application of radial load. |
