Summary:PROBLEM TO BE SOLVED: To simplify the operation and to improve the clamping force by coupling a printed circuit board and an iron plate to a motor casing by using one screw. SOLUTION: Through holes 36a, 38a in which a screw 42 is passed are opened at a printed circuit board 39, and a clamping tap hole 41a is formed at a position corresponding to the through hole of the plate 42. A burr is formed at the periphery of the hole 41a, and so coupled as to be inserted into the hole. Since the substantial thickness of the plate 41 is increased by the burr, the clamping force of the screw is improved, and the clatter of the board 39 can be prevented.
