ABSTRACT:
Spindle motors, one example being furnished with: a housing member perforated by a round through-hole; a sleeve disposed within the housing through-hole; a shaft; fluid dynamic-pressure bearings that support the shaft against the sleeve letting one rotate relative to the other; and an electroconductive member contacting on the housing member and the sleeve, and electrically interconnecting the two. An elastic limb that in its elastically deformed state contacts on at least either the housing member or the sleeve is formed on at least either the inner periphery or the outer periphery of the electroconductive member. By the spring force of the elastic limb, the electroconductive member contacts on the housing member and the sleeve, maintaining elastic stress between them.
