It is elastically deformed to the larger side and inserted into the hole. When the claw is completely inserted into the hole, the elastic force of the claw allows the claw to recover and automatically engage the bottom surface of the printed circuit board.

されている。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2E. A conductive rubber 13 is arranged between the liquid crystal display element 11 and the printed circuit board 12. Printed circuit board 12) A hole 12a is formed into which the claw portion 14a of the moss front panel 14 is inserted. The claw portion 14a of the front panel 14 is bent in advance so as to fit onto the bottom surface of the printed circuit board 12, and a tapered portion 14b is formed at the end of the bottom surface of this bent portion.

２の底面に係合する。Therefore, the claw portion 14a of the front panel 14 is attached to the printed circuit board 1.
When the tapered portion 14b is inserted into the hole 12af of No. 2, the tapered portion 14b comes into contact with the upper surface f of the printed circuit board 12. However, the tapered portion 14
As a result, the claw portion 14a is elastically deformed toward the hole 12a, so that the claw portion 14a is easily inserted into the hole 12a. When the claw portion 14a is completely inserted into the hole 12af,
The claw portion 14a is restored by the elastic force l, and the printed circuit board 1
It engages with the bottom surface of 2.

ことができるので、組立工数も低減する。In this way, simply by inserting the claw portion 14a of the front panel 14 into the hole 12al of the printed circuit board 12, the claw portion 14a engages with the bottom surface of the printed circuit board 12, so the assembly machine is equipped with a mechanism for bending the claw portion. This eliminates the need for the assembly machine to be installed, making it inexpensive and versatile, as well as allowing product changes to be made in a short time. Since this can be done in advance, the number of assembly steps is also reduced.
