The body frame 3 and the frame 5 of the motor 2 are generally formed by drawing. Due to the processing precision, the main body frame 3
The motor 2 mounting portion and the flange portion 6 of the motor 2 are in a situation where it is difficult to obtain horizontality.
When the motor 2 is attached to the main body frame 3 as described above,
As shown in FIG. 19, the mounting piece portion 8 of the motor 2 causes a “first contact” in which the tip end contacts the main body frame 3 and the other portions are separated from the main body frame 3 (in FIG. 19, the main body frame 3).
