As shown in FIG. 2, the tongue portion 4a that engages with the groove of the stator
When mounting on the stator, the tip of the tongue is inserted into the groove of the stator, is axially pressed, and is attached to the stator end surface. Conventionally, there is a method of pressurizing in the radial direction through other parts, but the present invention is designed to mount the frame directly to the stator without using other parts, thus eliminating the influence of distortion on the stator inner diameter. Therefore, the pressure is applied in the axial direction.
