<p>A motor and a method of manufacturing the motor are provided for preventing undesirable deformation of the sleeve hole caused by a press fitting force during press fitting process, thus facilitating the assembly process and improving the productivity. A recess is formed on an inner peripheral wall of a center cylindrical portion at the center of a flange body. When press fitting a sleeve body into a hole (sleeve fitting hole) of a flange assembly unit for integrating both members, the annular recess of the flange assembly unit serves to reduce the contact area between the sleeve body and the flange body. The press fitting force exerted to the contact area is reduced. Therefore the deformation of the inner diameter of the sleeve body that has been press fitted is minimized, thus suppressing deformation of the inner diameter portion of the sleeve body and the flange body. <IMAGE></p> |
