The second elastic members 98 are restored (relaxed) to their original state.

Each of the second elastic link modules 90 maintains an oblique state on the other side opposite to each other with respect to the moving direction of the first body 3.

Meanwhile, when the stroke (operation length) of the first body 3 is increased to secure a wider open area of the second body 5 when the first body 3 is opened, the first body (as described above) is increased. When 3) automatically moves upward in the remaining section and is fully open, the second elastic link module 90 is partially exposed to the outside of the upper edge of the second body 5.

In this case, as the first sliding member 10 moves upward, the sub sliding member 50 is provided through the slider 76 in a state where the engagement with the first sliding member 10 is released. It is guided to the second sliding member 30 by the elastic restoring force of the first elastic members 81 and slides upward in the remaining sections of the entire moving sections.

Accordingly, the sub sliding member 50 partially protrudes to the outside of the upper edge of the second body 5 when the first body 3 is opened, and covers the exposed portion of the second elastic link module 90. do.
