The mounting piece 20 of the cover member 18 is bent in a direction parallel to the sliding direction of the slider 24, so that the bending of the cover member 18 at the time of bending does not reduce the width of the cover member 18 and change the dimensions. The slider 24 can be fixed to the circuit board 10 without affecting the sliding performance. Particularly, in this case, since the cover member 18 forms a guide portion when the slider 24 slides, the dimensional accuracy of the cover member 18 is reduced.
This has a direct effect on the sliding performance, and the bending direction has a very important meaning.
