Abstract
In order to reliably lock a door element and detect its state, a pressing unit is mounted to a part of a door element so that it may press in the closing direction independently of the door body, and latch means is mounted to the mating part of the door element so that it may be engaged with a distal end of the pressing unit at a distance less than a predetermined spacing to finely move the door element. A projecting part is mounted to the pressing unit so as to project toward the mating part. The mating part includes resilient means acting to repel a force of the projecting part influenced in the direction of the mating part, and a switching element operable to detect the closing state of the door element when the projecting part presses the resilient means with more than a predetermined pressing force.
