The locking hole 140 is rotated about the third hinge shaft 122c. As the locking hole 140 rotates, the cam 144 rotates and contacts the base plate 121 to raise the third hinge shaft 122c than the first and second hinge shafts 122a and 122b.

Then, as illustrated in FIG. 10, the first hinge shaft 122a is formed by the elastic member 127 exerting a compressive force between the first hinge shaft 122a and the second hinge shaft 122b. The first tilt link 123 and the second tilt link 125 are moved from the inclined hole 121a 'to the horizontal hole 121a' 'along the slit shape of 121a. While forming the shape, the second member 2 provided with the movable plate 114 is inclinedly opened with respect to the first member 1 provided with the base plate 121.

On the other hand, when the user pushes the second member 2 to return to the closed state from the inclined open state with respect to the first member 1, the second tilt link as shown in FIG. While the push bar 126 provided at 125 is pushed by the push protrusion 114b of the movable plate 114, the inclination gradually decreases. Then, the third hinge shaft 122c is accommodated in the third hinge shaft hole 121c of the base plate 121 lower than the first and second hinge shafts 122a and 122b, and the movable plate 114 of the second member 2 is provided. ) Returns to the initial position of FIG. 6.
