Summary:In a motor, a motor housing includes a motor housing main body having a cylindrical portion and a lid portion holding a first bearing, a cover holding a second bearing, a stator housing forming a radial flow path between the inner peripheral surface of the cylindrical portion, first and second seal members, and a positioning portion for radially positioning the motor housing main body and the cover. The stator housing includes a stator housing main body and a flange portion positioned between the motor housing main body and the cover in the axial direction. The first seal member seals a gap in the radial direction between the cylindrical portion and the stator housing main body. The second seal member seals a gap in the axial direction between the motor housing main body and the flange portion. The positioning portion positions the stator housing in the radial direction with respect to the motor housing main body and the cover. 在本发明的马达的一个形态中，马达外壳具有：马达外壳主体，马达外壳主体具有筒状部和盖部，盖部对第一轴承进行保持；盖构件，盖构件对第二轴承进行保持；定子外壳，定子外壳在
