PROBLEM TO BE SOLVED: To prevent a projection part from being easily shifted in a circumferential direction to an abutting part while maintaining the easiness of the work of incorporating an armature to a base part.SOLUTION: In the armature, on an inner peripheral surface part of an insertion part where the projection part is provided on the outer peripheral surface and a bearing holding part 15 for rotatably supporting a shaft of a rotor part through a bearing member is inserted on the inner peripheral surface, an abutting part 45 abutted to the projection part from one side in the center axis direction of the shaft by energization of an elastic member, a center axis direction path part 46 for enabling the projection part to move relatively from one side to the other side of the center axis direction to the abutting part 45, a circumferential direction path part 47 for allowing relative movement by turning to the bearing holding part 15, and a flexible pawl part 48 for allowing first movement of the relative movement of the projection part from the center axis direction path part 46 to the side of the abutting part 45 and regulating second movement in the direction opposite to the direction of the first movement, are formed.
