A guiding device is attached to the door and slidable on the guide rail, and the door is housed so that one side of the door is substantially flush with one side of the wall when the door closes the opening. , in a sliding door that is slid and guided approximately parallel to the side surface of the wall by the guide device when the door is opened, a guide member having a longitudinal direction parallel to the sliding direction of the door is fixed to the other side surface of the door; The base of the rotary arm is rotatably supported in a substantially horizontal plane on a mounting floor that is fixed to the wall, and the drive pulley is arranged coaxially with the center axis of rotation of the base of the rotary arm. A driven pulley and a guide roller are rotatably supported on the base, and a driven pulley and a guide roller are coaxially rotatable at the free end of the rotary arm via a support shaft parallel to the rotation center axis of the base. A driving wheel having a cylindrical outer circumferential surface made of a material having an appropriate coefficient of friction is concentrically fixed to a part of the driven pulley in the axial direction, and the guide member is forming first and second guide edges extending in a substantially vertical plane along the longitudinal direction and opposing each other at an appropriate interval in a substantially horizontal direction, the first and second guide edges of the guide member; The circumferential surface of the drive wheel is abutted against one of the mutually opposing surfaces of the edges, and the circumferential surface of the guide roller is abutted against the other, and the output shaft of the prime mover is attached to the mounting floor or the base of the rotating arm. Since the drive pulley is rotatably connected to the drive pulley via a speed reduction device, and the drive pulley and the passive pulley are also rotatably connected, the guide device attached to the door and the guide rail attached along the wall. Due to the engagement relationship, when the door is moved parallel to the wall and there is almost no resistance to the movement, the torque of the prime mover exclusively drives the drive wheel to rotate, and the drive wheel is pressed into engagement. A driving force is applied to the door in the direction along the wall through a guide member having a guide edge, and when the guide device attached to the door engages with the curved part of the guide rail and creates resistance to the rotation of the drive wheel, The output torque of the prime mover rotates the rotating arm via the final power transmission means such as the final gear of the reduction gear, and generates a propulsion component in the direction perpendicular to the wall surface on the door, causing swinging or retracting motion. an opening movement or a door in which a door housed in an opening in a wall is swung out and slid onto the outer surface of the wall by rotation of a single prime mover in a single direction, regardless of the shape of the guide rail. The closure movement is achieved by sliding along the outer surface of the wall and retracting it into the opening.
