ABSTRACT:
A motor may include a bearing made of resin for rotatably supporting one end part of the rotor shaft, and an urging member attached to a bearing holder and abutted with a pressurization face of the bearing to urge the bearing toward a side of the rotor shaft. A molding material injection gate trace (projection) which has been used when the bearing is resin-molded is positioned at a center portion of the pressurization face. The molding material injection gate trace may be positioned in a recessed part which is formed at a roughly center portion of the pressurization face of the bearing. Further, the urging member may include an urging piece which is formed by cutting a center portion of a metal plate in a ring shape and an opening part is formed in the urging piece.
