PURPOSE:To smooth rotation and slide motion at the time of opening or closing a door, by checking any slide motion of the door at the time of projection motion due to rotation of a door supporting arm, and constituting an opening/ closing mechanism to check the arm rotation at the time of the slide motion of the door. CONSTITUTION:When a door is displaced to the outside at the time of its opening, both inner and outer arms 5 and 6 are rotated, but a sliding lock plate 18 and an arm lock plate 21 keep their angles, whereby movement of a guide plate 16 is checked. After that, shafts 17 and 20 come to the same axis whereby their turndown motion comes possible, and when the door is moved to the rear, a guide pin 19 is displaced along a groove 16a, and rotation of these inner and outer arms 5 and 6 is checked. With this constitution, door sliding motion is checked during rotation of each arm, and since arm turning motion is also checked during door sliding motion, rotation and sliding motion at the time of opening or closing the door can be done with moderation, and simultaneously operating transition from rotation to slide motion and vice versa is smoothly and accurately performable.
