<P>PROBLEM TO BE SOLVED: To provide an opening restriction device that improves convenience in putting a face plate back into a restricted state after placing the face plate in an unrestricted state, and fittings. <P>SOLUTION: A cylinder lock of a moving member 30 can be placed in a locked state by moving the moving member 30 to an opening maintaining part of an arm member 21 by rotating a paper sliding door 10, having been opened up to a non-restriction range, in a closing direction, and the paper sliding door 10 can be put back into a restricted state without user's locking operation for the cylinder lock. Therefore, the paper sliding door 10 can be automatically placed in a restricted state without being put back into the restricted state by a user. The security can be ensured by restricting the opening angle of the paper sliding door 10 within a restriction range up to a first angle, and no user needs to perform locking operation, so that the convenience is improved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
