PURPOSE:To easily perform clearance between a bearing and an armature shaft by providing a thin part for alignment being made in thickness dimension smaller than the thickness of the board of a case, outside the bearing of the case. CONSTITUTION:The inside diameter of a second bearing mount 5b where a bearing 6 on the side of an end cover is mounted is a little larger than the outside diameter o the bearing 6 on the side of an end cover, and at a thin part 5c for alignment is made a recessed groove 5c1, which is made in a ring shape from the inside and the outside of a motor yoke 2 to the body 5a of an end cover. And, if a pipe-shaped jig is pushed in the thin part 5c and then is pressed to prize the thin part 5c, the recessed groove 5c1 bends, and inclines the second bearing mount 5b on the body 5a of the end cover, and inclines the direction of the opening of the armature shaft insertion hole of the bearing 6 on the side of the end cover. As a result, the amount of clearance between the armature shaft and the bearing can be adjusted easily after incorporating the armature into the case.
