Abstract

PURPOSE:To prevent the generation of knocking sound by interposing and inserting a buffer material in the gap between the end of a ball bearing and the end of a housing supporting section. CONSTITUTION:A rotary shaft 6 holding a rotor 7 mating with a stator 8 is supported with a housing 1 through ball bearings 11, 12 and the bearings are elastically supported by interposing elastic rings 13, 14 between the external circumference of outer races 11A, 12A and the internal circumference of housing support sections. And the ball bearing 12 is energized to unidirection by a pressure spring 16 and a buffer member 15 consisting of an elastic body is arranged at the end positioning to the opposite side of the pressure bearing for the ball bearing. In this way, the buffer member 15 is got between both ends 11D and 9A and compressed and deformed to fill up the gap. Therefore, the generation of knocking sound can be prevented.
