Abstract: A door which closes an opening in a container body of a thin plate container. A door body has latch passage holes in the circumference thereof, which correspond to latch recesses in an inner circumferential surface of the opening, and a component installation space. A rotary cam is received in the component installation space and is rotated by manipulation. Latch arms, each having one end connected to the rotary cam in the component installation space, reciprocate depending on a direction of rotation of the rotary cam so that free end areas thereof enter or exit the latch recesses through the latch passage holes. When the rotary cam rotates in a locking direction, the latch arms move along straight lines until at least portions of the free end areas are inserted into the latch recesses and then pivot so that the free end areas are pressed toward the container body.
