When the opening / closing part 15 is closed, it is held by the hooking part 4 of the hooking part 1 which is fixedly connected to the installation part 19. By pushing the hook portion 1 in the W1 direction, the hook portion 4 is released, and the spring force of the torsion spring 10 attached to the fulcrum portion 6 pushes the hook portion 4 upward to open and close it.

There is a drawback in that when the hooking portion for releasing the hooking portion is pressed and the hooking portion is pushed, the flip-up mechanism cannot be used and the hooking portion must be opened and closed while being pressed. Further, since it works at a position very close to the fulcrum, there is a drawback that the force for pushing up the opening / closing part becomes large and the weight of members such as springs becomes heavy.

The hooking portion 4 connects the opening / closing portion 5 to the installation portion 9.
At this time, the convex portion 8 provided on the opening / closing portion 5 pushes the elastic body 7 of the installation portion 9. At the time of opening, the hook 4 is disengaged by pushing in the W1 direction around the fulcrum 2 against the spring 3 attached to the hook 1, and at the same time, the elasticity of the elastic body 7 causes the opening / closing part 5 to move to W2. It is flipped up in the direction and becomes free. Further, even when the hand is released during the operation of closing the opening / closing portion, the elastic body reduces the impact on the opening / closing portion.

る。As described above, according to the present invention, since the point of action for pushing up the opening / closing portion is provided at a position away from the fulcrum, the pushing force of the elastic body can be small and the weight of members such as springs can be reduced. , A flip-up mechanism is provided by having a hooking part that connects the fulcrum side and the opposite one when the opening / closing part is closed, and an elastic body contact that automatically opens and closes the hooking part when the hooking part is released. realizable. Further, even if the hand is released during the operation of closing the opening / closing portion, the elastic body has an effect of reducing the impact of the opening / closing portion.
