PROBLEM TO BE SOLVED: To make it possible to easily set shaking prevention for a door by fixing the basic end side as a joint side with a handle passing through from the surface side to a through-hole of a main body case to make the front end as a free end, and mounting an elastic plate interlocking with a box body to a chain lock plate. SOLUTION: A chain lock plate 3 is connected to a joint shaft 7 of a handle 2 passing through from a through-hole on the rear side of a main body case 1, and a door is locked or unlocked. The front end side of the chain lock plate 3 is formed in the shape of a fork, and an elastic plate 14 for making the front side as the free end is welded between the front ends 3a and 3b thereof. In a process for the chain lock plate 3 to move while bringing the elastic plate 14 into contact with the rear side of the box body, both sides of the elastic plate 14 make position control between the front ends 3a and 3b formed in the shape of a fork, and the elastic plate 14 is difficult to slip from the chain lock plate 3. When the handle 2 is turned from a projected state of the handle 2, a contact section of the elastic plate 14 is brought into contact with the rear side of the box body, and the elastic plate 14 is naturally bent to make it possible to prevent shaking of the door. |
