Abstract
Provided is a configuration where a stator section is fastened to an electric motor part-accommodating portion at a location where an end surface of the stator section projects outwardly from an end plane of an opening of an electric motor part-accommodating portion thereby bringing the center of gravity of an electric motor part closer to the end plane of the opening of the electric motor part-accommodating portion. With this, the center of gravity of the electric motor part is brought closer to the end plane of the opening of the electric motor part-accommodating portion so as to make a rotor section difficult to receive the influence of oscillations, and consequently a phenomenon where the rotor section is shaken under the influence of oscillations can be restrained.
