CONSTITUTION: A lid body 13 is provided to an axis 14 provided to a case main body 10 through a spring 15 and slot 18 for sliding and swinging, while a lock device 26 comprising a recess 30 engaging with the lid body 13 is provided for free swinging. At opening of a lid, the lid body 13 is pressurized against energized force of a leaf spring 29 to release the engagement with the lock device 26, and then the lid body 13 is slid perpendicularly to the pressurizing direction for opening. When closing the lid, the lid body 13 is pressurized and then slid to lock. Thus a double lock method is provided. So, accidental opening of a lid is prevented.</p> |
