Abstract
A housing is provided with a partition wall portion that partitions an inner space of the housing into an electric motor accommodating space and a speed reducer accommodating space. The partition wall portion fixes a gear that constitutes a speed reducer. In addition, the partition wall portion has a housing boss portion, and an inner stator is fixed to the housing boss portion. Thus, heat generated by the inner stator is dissipated to the outside through the housing boss portion and the partition wall portion.
