A motor includes a cylindrical stator. The stator includes a stator core having teeth, which project inwardly in the radial direction, and coils, which are formed by winding a conductive wire onto each tooth with first and second insulators. The first insulator includes a support extending axially from an outer restriction wall. Each of first to third bus bars is supported by the support of the first insulator in a state in which a main portion is exposed. The main portions of the first to third bus bars are thus in contact with ambient air.
