PURPOSE:To improve operability in mounting/demounting by projecting a stopper segment back and forth at the center section on the upper surface of a socket member comprising a connecting section. CONSTITUTION:When a lid main body is demounted, a lock pin is disengaged from a locator hole, a connecting plate 8 is pulled out of the opening 5 of a socket member 4 with a lid side section raised up while the bottom section of a slider 16 is swung over the base of a stopper segment 15. And when the same is mounted, the slider 16 is engaged with the base of the stopper segment 15 while being butted in such a way that the lid main body 7 is swung with fulcrum at the base of the slider 16. Owing to this constitution, the swing locus of the connecting plate 8 is made approximately definite for preventing the lid main body from biting the socket section so as to improve operability as well as to prevent the lid main body from being damaged. |
