BEARING AND BEARING DEVICE

摘要

A bearing member comprising highly accurate dynamic pressure generating portions and stably manufacturable at low cost. Dynamic pressure grooves (8a1) and (8a2) as the dynamic pressure generating portions are formed in the inner peripheral surface of an electroformed part (10) by electroforming, and the electroformed part (10) is inserted and the bearing member (8) is injection-molded with a resin. A shaft member (2) is inserted to the inner periphery of the bearing member.
