PURPOSE:To facilitate manufacture and handling and to maintain good appearance by providing a hook lever arranged rotatably on the rear face of door, a lock member with which the door locks the board face, and a resilient member for maintaining a locked state of a hook section and the lock member. CONSTITUTION:Operating section 2B of hook levers 2 mounted at the opposite sides on the rear face of a door 1 is operated reversely from the direction (a) of a lock member while resisting against the resiliency of a spring 7, with the lower end of the door 1 being supported by a board side receiving metal 11 arranged on the board face 9, then a hook section 2A is locked with the lock member 10 of a board side fixed frame 9A through the spring 7 and the locked state is maintained thus closing the board face 9 with the door 1. By such arrangement, the structure is simplified, handling is facilitated and good appearance is maintained. |
