１項記載の扉の開閉装置。[Claims for Utility Model Registration] 1. A door 4 that opens and closes while rotating around a support shaft 3 provided horizontally at its base end, and a drive shaft 6 provided perpendicular to the support shaft. A movable nut 11 is screwed into the door so as to be relatively rotatable, and the movable nut 11 is connected to a support point provided at a position away from the proximal end of the door toward the distal end side and in the vicinity of the support shaft, respectively, and is connected to each other by a pin. 1st, 2nd

A door opening/closing device, wherein the stopper restricts movement of the moving nut at a position where a relative angle between the first and second link arms exceeds 180 degrees. 2. A request for registration of a utility model, characterized in that a connecting part 10 to which a manual operation handle 9 is detachably connected is provided at the upper end of the rotating shaft, and a drive motor 8 is provided at the lower end of the rotating shaft. The door opening/closing device described in item 1.
