The arm 2 is rotated while the grip 13 is gripped by the gripping member 5 for releasing the rocking wing 12, the arm 2 is rotated inversely after stopping, and then the grip 13 is released from the gripping member 15 halfway for closing the swinging wing 12, thus switching the swinging wing automatically. Also, the gripping member 5 is fixed to the post 4 so that it can travel freely in length and height directions of the arm 2 to cope with the change in scale of the swinging wing 12. |
