Abstract
A motor includes a stator having a stator core, a rotor, a case, and a bearing. The motor may further include a bearing hold member provided with a through hole into which the bearing is inserted and which is disposed at one end side to the stator core and a spring member held by the case such that at least one part of the spring member overlaps the bearing hold member at one end side to the bearing hold member to urge the bearing in the through hole to the rotor shaft. A first positioning projection is formed in one of the stator core and the bearing hold member so as to protrude on a side of the other and a first fitting hole is formed in the other of the stator core and the bearing hold member so as to be fitted to the first positioning projection.
