PURPOSE:To facilitate assembling and to mount an opening and closing cover to a slope part in space saving manner by unifying the cover receiver of the opening and closing cover with a case and mounting a fixing spring on a printed circuit board. CONSTITUTION:A printed circuit board 3 having a fixing spring 2 mounted thereon is fixed to a case 1 by a screw 4 and an opening and closing cover 5 is obliquely inserted in the gap between the A-point of the case 1 and the B-point of the cover receiving part 6 of the case and pushed in on the side of the cover receiver 6 when the rear part of the cover enters the hole of the case 1. The guide pawl 7 provided to the opening and closing cover 5 is bitten with the cover receiving part to prevent the spring-out of the cover 5 from the case 1. When a moving projection 8 is pushed to be moved until the opening and closing cover 5 strikes at the case 1, the opening and closing cover 5 is fixed to the inner wall of the case 1. |
