The first case has a wall part covering the other side in the axial direction of a stator and having a through hole. The bearing holder has: a holder cylindrical part holding the first bearing and inserted into the through hole; and a holder flange part fixed to the wall part. An inner diameter of the through hole is larger than an outer diameter of the holder cylindrical part. At least a part of a radially outer surface of the holder cylindrical part in a circumferential direction is located in a position radially inside and away from a radially inner surface of the through hole.
