Next, the operation and effect of the first embodiment having the above-mentioned constituent sounds will be explained.

Now, in this example, the spring member 6 has a flexible portion 3b that is held in an inverted posture when it protrudes above the Q support point S1, and that both flexible portions 6b in this inverted posture are pressed downward to close the cover. When the point of action S2 of the spring portion 4A6 on the member 1 is displaced below the regular support point S1, the two bent portions 6b exceed the turning point of the deflection direction and are held in an inverted curved posture. It has been given the power of orange bullets.

For this purpose, the spring member 6, which is supported at both ends by Z, is pushed out above both support points S1, and the latching part 8 of the engaging part 6C is attached to the ceramic body.
When the line layer m1bK of the cover member 1 is stopped and the cover member 1 is pressed downward, the spring member 5 is deflected HK3.
As a result of bending b in an inverted manner and urging the cover member 1 downward, the cover member 1 can be stably installed on the frame by the spring member 6 on K'.

Therefore, it is possible to simplify the engagement and disengagement of the cover member 1 to and from the spring member 6, thereby significantly simplifying the attachment and detachment of the cover member 1 to both bodies, and to reverse the curved posture of the flexible portion 6b. Since the cover member 1 is attached and separated with a force of inversion<Is, it is possible to reduce variations in the pressing force on the cover member 1 and increase the pressing force.

In particular, in the case of the elliptical 1 example, both ends of the spring member are connected to both ends of the spring member y:,
, K Since it is directly fixed, the bending direction f of the bending portion 6b can be reliably reversed, and there is an effect that the structure of the member 474 can be made smaller.

In addition, in this example, since the elastic force is different between the inside and outside of the flexible portion 6b, the reversal behavior of the flexible portion 3b becomes smooth and constant, and the reaction of the pressing force between each spring member can be reduced. can.
