[Effects of the Invention]
As shown in FIG. 1, when the lid 15 is in the closed position, the fourth horizontal pivot 11 is on the opposite side of the first horizontal pivot 5 with respect to the straight line connecting the third horizontal pivot 8 and the second horizontal pivot 1. The elastic force of the compression spring in the gas damper 13 acts as a force for rotating the first arm 2 in the clockwise direction in FIG. 1 about the second horizontal pivot 1. Therefore, the lid 15 is stably held in the closed position.
[0009]
When the lid 15 is pulled forward and the fourth horizontal pivot 11 crosses the straight line connecting the third horizontal pivot 8 and the second horizontal pivot 1 to the first horizontal pivot 5 side, the elastic force of the compression spring in the gas damper 13 Acts as a force for rotating the first arm 2 counterclockwise in FIG. 1 about the second horizontal pivot 1.
