Abstract
PURPOSE: To prevent noise from producing by shifting the specific frequency of the coil cover.
CONSTITUTION: Two ribs 10, 10' are formed by drawing on a coil cover 9a in the vertical direction. By providing the ribs 10, 10', the cover 9a increases in its rigidity and the specific frequency of the cover 9a shifts toward higher range. Thus, there is caused no noise.
