PROBLEM TO BE SOLVED: To provide a lead plate mounting mechanism for preventing detachment of a screw for fixing a printed circuit board upper terminal stand and a lead plate to which vibration is always applied.SOLUTION: The lead plate mounting mechanism comprises: a screw fixing a lead plate; a washer; and a terminal stand having an upper face on which a screw mounting hole is formed, which has a projection shape in a screw fastening direction and which is made of a material with lower strength than those of the screw and the washer. The lead plate and the washer are arranged on the upper face of the terminal stand and screwed with screws. Therefore, the terminal stand is deformed and a force is applied from a periphery in a screw center direction in which the screw is fastened, and there is no possibility for coming off of the screw mounted to the terminal stand having a screw detachment prevention mechanism. |
