PROBLEM TO BE SOLVED: To allow the movement of a movable member back and forth synchronized with a lid simply moving back and forth. SOLUTION: A door member 3 held movable back and forth by the lid 2 includes gear devices 6 for moving the door member 3 associated with the back and forth movement of the lid 2. As the upper gear 61 in the gear device 6 is forcibly rotated in one direction by a lower gear 60, the door member 3 moves ahead from the lid 2 when the lid 2 moves ahead and closes an opening 11 ahead of the lid 2.
