At this time, the rotation fastener 112 of the first insulating member 110 is also rotated while drawing the center. In addition, the wire spring 130 is compressed by the pressing force applied to the slide plate 20 and the elastic force starts to occur.

On the other hand, the elastic member module 100 according to the present invention is to provide a more reliable elastic force by using the elastically deformable material also the elastic support 120 when elastically compressed by the sliding of the wire spring (130). do.

Next, in the moving state of the slide plate 20, the wire spring 130 is provided with an elastic force while being further compressed by the pressing force.

In addition, the slide plate 20 passes through the inflection point in the process of moving to the open state, and the wire rod 130 is compressed and unfolded while passing through the inflection point. That is, the wire spring 130 is to apply the elastic restoring force of the slide plate 20 while passing through the inflection point. Then, the slide plate 20 is slid by the restoring force and moved to the finally opened state.

When the slide plate 20 is moved from the open state to the closed state, the slide plate 20 undergoes the reverse process of the driving process described above.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. It is not.
