Abstract
A stator core is sandwiched between a first frame and a second frame. A fastening member fastens the first frame and the second frame. The first frame includes a ring flange that is in contact with an attachment surface of the motor attachment portion. The flange includes a fixing portion fixed to the attachment surface and a fastening portion, which receives fastening force by the fastening member. The first frame includes a deform suppression portion for suppressing deformation of the fixing member when the fastening member is fastened.
