The connection member 4 is engaged with a guide groove part 3B of the second base member 3 and is further moved toward left, then the connection member 4 is connected to the second base member 3, the connection member 4 is stopped and positioned by an edge part 3C of the second base member 3, and a locking member 5 is brought into a fittable state to the second base member 3. When the locking member 5 is pushed down with respect to the connection member 4, a locking part 5A of the locking member 5 is fitted and locked to a fitting groove 3D of the second base member 3 via a hole part of the connection member 4. In the case of unlocking, the locking member 5 is pushed up with respect to the connection member 4, the connection member 4 is slid toward right and thereafter the doors are opened. |
