To make parts of a motor unit and a brake unit common between right and left.
A motor case member 100 and a brake case 200 are joined mutually and fixed in such a way that connections 101 to 103 are arranged in the motor case member 100 or a part of the motor case, that connections 201 to 203 are arranged in the brake case 200, and that the connections 101 to 103 are joined to the connection 201 to 203, respectively, using bolts. Furthermore, with respect to an axis of symmetry AS parallel in a back and forth direction of an electric vehicle, a plurality of connection in the motor case member 100 has a linearly symmetrical structure in a perpendicular direction of the electric vehicle, and a plurality of connection in the brake case 200 has the linearly symmetrical structure in the perpendicular direction of the electric vehicle too.
