ABSTRACT:
A door shutter is disposed in a device having an opening, and side portions for defining the opening. The other side of the opening extends higher than the one side. Guide grooves are formed along the side portions. The shutter includes main bodies bendable in a sliding direction for opening and closing the opening on the device, and projecting portions projecting from lateral sides of the main bodies in a width direction thereof and slidably engaging the guide grooves. The main body has first and second sides corresponding to the one and the other sides of the device. The wall thickness at the second side is thicker than that at the first side corresponding to the other side to form a substantially uniform surface from the one to the other sides through the main bodies.
