a tubular housing that fixes the stator from an outer peripheral side, wherein
the housing has a flange extending in an outer peripheral direction at an axial end portion of an outer peripheral surface, and
the flange has a recess extending in a circumferential direction, and a plurality of tabs are formed on the flange,
wherein the tabs comprises at least a pair of first tabs and at least a pair of second tabs longer in a circumferential direction than the pair of first tabs, the pair of first tabs being located so as to face each other with respect to a center of the housing, and the pair of second tabs being located so as to face each other with respect to the center of the housing, and each of the first and second tabs is provided with a hole,
wherein a projection is formed in a radially inner peripheral portion of the housing, and on an opposite surface of a portion in which the recess is formed.
