った。Of course, if a locking device that engages and disengages when opening and closing the lid is used without unlocking and turning operations, the complicatedness at the time of opening and closing can be eliminated. The engagement and the disengagement are performed by an operation or a pulling operation. Therefore, if the engagement of the locking device is set firmly in order to surely close the lid, the engaging operation force at the time of closing becomes large, and there is a disadvantage that the disengagement operation becomes difficult. When the engagement of the locking device is weakened to facilitate the engagement, the operating force at the time of closing becomes small and the disengagement becomes easy, but the closure of the lid becomes uncertain.
