The second housing includes a bearing holding portion holding a bearing of the shaft, a stator holding portion outside the bearing holding portion and holding the stator, and a coupling portion coupling the bearing holding portion and stator holding portion. The dimension in the axial direction of the shaft is a first dimension and the dimension in the circumferential direction of the shaft is a second dimension among dimensions of the end portion of the coupling portion on the bearing holding portion side. The first dimension is smaller than the second dimension. A portion of the coupling portion has a dimension in the axial direction smaller than the first dimension.
