る上で有効である。In the above-described configuration, the printed wiring board 35 on which the lower limit setting volume 31 is mounted has the plate body 4 in its thickness direction.
And is firmly held by the plate 11 without rattling,
In the direction orthogonal to the thickness direction, the holes 36 of the auxiliary heat radiating plate 10 ensure non-rotatable positioning and secure a large mounting strength. Therefore, when rotating the operation unit 33, the lower limit setting volume 31 does not wobble and it is difficult to operate. Here, in order to prevent rattling of the printed wiring board 35, the thickness of the printed wiring board 35 may be made equal to or slightly thicker than the thickness of the auxiliary heat dissipation plate 10, and may be made thicker. In this case, it is desirable that the printed wiring board 35 has a thickness similar to that of the compressed auxiliary heat dissipation plate 10 due to the sandwiching force between the plate body 4 and the plate 11. In addition, the size of the printed wiring board 35 and the auxiliary heat sink 10
Matching the size of the holes 36 with the holes 36 is also effective in eliminating rattling.

る。(G) Effect of the Invention According to the electrical component mounting structure of the present invention, the board on which the electrical component is mounted is securely and firmly held in the thickness direction and in the direction orthogonal to the thickness direction, and the size of the electrical component is large. Regardless of the size, a large mounting strength is secured. The rotation of electric parts is also prevented. Therefore, the mounting location is not restricted even for a small electric component having a rotary operation part, and it can be particularly suitably used for a mounting structure of such a small electric component. Further, since the mounting screw is not used, the work of tightening the mounting screw is unnecessary, and anyone can easily and surely mount the electric component.
