MOTOR

To provide a motor capable of suppressing warpage of an attaching part at the time of attaching a case to another component.SOLUTION: A case 2 of a motor 1 is formed into a cylindrical shape with an open part 20 at a top edge, and a stator is fixed within the case. An end frame 10 is fixed to the top edge of the case 2 so as to block the open part 20. At a flange 23 of the case 2, a plurality of attaching parts 24 bolted to another component is formed so as to project in a diametrical outside direction of the case 2. A plurality of press-fitting parts 104 press-fitted to an internal surface 22 of the case 2 is provided on the outer periphery of the end frame 10. Each press-fitting part 104 is provided at a position spaced apart from a center of a bolt hole 26 formed in the attaching part 24 by a predetermined angle in a circumferential direction of the case 2. When the number of the press-fitting parts 104 is supposed to n, a predetermined angle θ1 (degree) is set to a value satisfying an inequality of 360/8n
