<p>PROBLEM TO BE SOLVED: To solve problems that the lock of a door 20 at the rear section of a truck box-type body van and a container has a mechanical structure locked by the meshing between a pawl 19 and a guide 9 fitted to the tips of a lock shaft 1 and a lock shaft 16 by the rotation of a handle 3 fitted to the lock shaft 1 in Fig. 5, therefore handles 3 interfere with other portions when a plurality of handles 3 are fitted to one door 20, and the external appearance is deteriorated because the handles 3 are exposed. SOLUTION: The lock shaft 1 is rotated for locking and the handle 3 is stored below, therefore the handle 3 does not interfere with other portions in this system, unlike the conventional system that the handle 3 is rotated to lock the door 20 and the handle is stored on the side. Since the handle 3 is covered with a lock cover 2, the external appearance becomes neat and nice to look at, and the double-lock mechanism of the handle is attained, thus the problems can be solved.</p> |
