This has the effect of preventing them from being damaged by sunlight, wind and rain, and maintaining the locking function for a long life.

However, even if the locking structure is located inside the case and cannot be seen from the outside as described above, in order to open the lid, all you have to do is push up the lock release piece 45 located on the outside from below. The lock release piece 45 can be used to move the lid 10 upward and push its lower part forward to release the lock as described above.Then, all you have to do is pull up the lower part of the lid 10 toward you to open it. On the other hand, when closing the lid 10, the lid 1
Just by closing the lid 10 and pushing its lower part toward the main body 4, the lid 10 can be automatically locked in the closed state as described above.
The effect is that both opening and closing operations can be performed extremely easily.

Furthermore, in the present invention, even if the external lock release piece 45 is damaged or lost, the lock release piece 45 is separate from the lid body 10 and does not itself have the function of vertical movement. In other words, even if the lock release piece 45 is not present, there is no effect on the ability to move the lid 10 upward and to draw the lower part of the lid forward, so there is no lock release piece 45. Even after aging, the lid body 1
It is also useful in that it can maintain the opening/closing function of 0 and the locking function in the closed state.
