1B, 1C, and 1D, the metal upper case 3 is engaged with the hole 12 formed in the lower case 6 at the lower end of one of the side walls 1B of the opposing side walls 1B, 1D, and the hook facing inward. A claw portion 13 is formed. The claw portion 13 has an obtuse angle of 90 ° + α with respect to the side wall. A screw hole 5 provided in the mounting piece 5 of the lower case 6 is provided outside the lower end of the other side wall 1D.
Two mounting pieces 2 each having a screw hole 2A corresponding to A are formed.

下ケース６との組みつけ後のガタつきが防止できる。The method of assembling the printed circuit board 8, the upper case 3 and the lower case 6 is as follows. The printed circuit board 8 is moved to the lower case 6 in the direction of the arrow in FIG. Then, the claw portion 13 of the upper case 3 is locked in the hole portion 12 of the lower case 6. At this time, since the claw portion 13 is formed at an obtuse angle with respect to the side wall 1B, the claw portion 13 comes into contact with the bottom surface 11 of the lower case 6, and a force acts in a direction of pressing the bottom surface 11, thereby mounting the upper case 3. The piece 2, the printed circuit board 8, and the mounting piece 2 of the lower case 6 are fixed by screws 9, so that rattling after the upper case 3 and the lower case 6 are assembled can be prevented.

When forming 10, the hole 12 is first formed, and then a cut is made to form the cut-and-raised portion 10, and the cut and raised portion 10 is protruded inward by pressing with a press. With such a configuration, the cut-and-raised portion 10 for holding the printed circuit board 8 and the claw portion 13 of the upper case 6 are engaged with each other.
It is not necessary to separately form 12 and 12, and they can be formed at the same time, and the number of steps can be reduced.
