摘要： PROBLEM TO BE SOLVED: To prevent seizure of a lower bearing so as to realize a thin and lightweight lower housing by providing rotation preventing means for regulating the relative rotation in the specified position in which a stator faces an upper housing or a closed casing faces the lower housing. SOLUTION: Only positioning of the vertical direction and the center of a lower housing 6 is performed by fitting and holding force generated by press- fit of the lower housing 6 and a stator 41, and prevention of relative rotation of the lower housing 6 to the stator 41 is performed by locking a head part 33a of a bolt 33 on a groove 6a. Therefore, press-fit margin between the lower housing 6 and the stator 41 can be relatively decreased. As a result, press-fit distortion to be generated by fitting of the lower housing 6 to the stator 41 is reduced, and deformation of a lower bearing 61 is restrained. It is unnecessary to increase the wall thickness of the lower housing 6, for restraining the distortion amount of the lower housing 6.
