PROBLEM TO BE SOLVED: To provide a door locking mechanism, by which a door is locked automatically with the closing operation of the door. SOLUTION: The closing engaging edge and receiving piece of the door are formed to a box body. An opening section corresponding to the closing engaging edge of the box body is formed to an internal plate for the door, and the opening section and a supporting frame are formed and mounted to the internal plate for the door installed to the box body in a rockable manner. A sliding plate in which an engaging section is formed at a front-end edge and a projecting piece is formed at a rear-end edge is arranged so that the projecting piece at the rear-end edge is engaged with the receiving piece of the box body in the case of the closing operation of the door and slid towards the opening section of the door. The rear end of an open-close operating member is engaged with the engaging section for the sliding plate while the front-end edge is extended up to the front end of the opening section of the internal plate, and the door is pivotally supported movably along a dogleg-shaped slot extended in an inclined shape towards the inside of the closing engaging edge of a box.
