PROBLEM TO BE SOLVED: To resolve a problem that a door is moved by the prescribed distance to the door opening side when one side of the door is opened, opening resistance is liable to occur due to the friction between the door and the contact main body side such as a portion supporting the door when the door is moved, and the load for opening the door is larger than that of an ordinary hinge type door. SOLUTION: Cam mechanisms 22, 40 provided on both sides of the door 2 to couple or release the door 2 and the main body can be set to a first lock position and a second lock position symmetrical on both sides of the door 2. The cam mechanisms 22, 40 on both sides are set to the first lock position in the closed state of the door 2. When one of the cam mechanisms 22, 40 on both sides of the door 2 is released, the door 2 is moved by the prescribed distance to the opening side of the door 2 to the second lock position, and the door 2 is rotatably locked at the second lock position. For opening the door 2, the door 2 is moved and separated by the prescribed interval by a lever means provided on the door 2.
