A door includes a door body, a pair of rotating shafts, a pair of opening/closing levers and an inhibiting member. The pair of rotating shafts rotate the door body toward either one of the left and right directions. The pair of rotating shafts are provided on each of the left and right sides of the door body. The pair of rotating shafts are vertically slidable. The pair of opening/closing levers are provided on each of the left and right sides of the door body. The opening/closing lever is connected to the rotating shaft on the same side of the door body. The opening/closing lever acommodates the connected rotating shaft within the door body by rotation. The inhibiting member inhibits one of the rotating shafts from being accommodated within the door body by operating simultaneously with rotation of the opening/closing lever connected to the other rotating shaft.
