Patent ID: 7535141

Claim:
A motor comprising: a ring-shaped stator including stator cores having a plurality of pole teeth disposed in a circumferential direction in an inner peripheral face of a rotor disposing hole; a rotor; a case which accommodates the stator and a base end side of the rotor; a bearing which receives a shaft end of a rotor shaft of the rotor at one end side of the case; a bearing hold member which is provided with a through hole into which the bearing is inserted and which is disposed at the one end side to the stator such that at least one part of the bearing hold member overlaps the stator; a spring member which is held by the case such that at least one part of the spring member overlaps the bearing hold member at the one end side to the bearing hold member, and which is provided with a spring part that urges the bearing in the through hole to the rotor shaft; a first positioning projection which is formed in one of the stator core and the bearing hold member so as to protrude on a side of the other of the stator core and the bearing hold member; and a first fitting hole which is formed in the other of the stator core and the bearing hold member, and to which the first positioning projection is fitted; wherein the bearing hold member is provided with a ring-shaped projection for positioning which is protruded from a circumference of the through hole toward the stator, and the ring-shaped projection is inscribed on inner peripheral faces of the pole teeth so that the bearing hold member is positioned in a radial direction by the inner peripheral faces of the pole teeth.
