6 and rotated 90 degrees clockwise, the inner cylinder 6 also rotates 90 degrees, and the latch 11 comes off the receiving plate 3 of the fixed wall 2 and is unlocked. At this time, two groove portions 9 symmetrical with respect to the central axis.
Are moved from the groove upper end 9a to the groove intersection 9b. Accordingly, the inner cylinder 6 has a difference in height between the groove upper end 9a and the groove intersection 9b (for example, about 5 mm).
Move up. Then, the inner cylinder 6 further projects by screwing the eye nut 17 into the male screw portion 7 of the inner cylinder 6 that has protruded from the upper end of the fixed cylindrical body 4 and rotating it.
Since the set screw 14 moves from the groove intersection 9b to the groove lower end 9c, the inner cylinder 6 further moves further upward (for example, about 7 mm) in height between the groove intersection 9b and the groove lower end 9c, and is unlocked. For example, it is fixed while being raised by about 12 mm. To the eye nut 17, a terminal portion of a lifting machine is attached when the heavy lid 1 is opened and closed.

Is fixed by passing a mounting tool such as a bolt through the lid mounting hole 5a. The back cover 13 is fixed to the fixed cylinder 4 by welding at several places. After the inner cylinder 6 is inserted into the fixed cylinder 4, the latch 11 is welded all around the shaft 10. The set screw 14 is screwed into the fixed cylinder 4 so as to be engaged with the groove 9, and is welded after performing an operation test.
