The driving source horizontally drives and is located in the side of a bath(14). One end of the rotary link is hinged with the side of the bath separated in parallel with the driving source to rotate. The connection link is arranged between the driving source and the rotary link. The first driving link is hinged with one end of the connection link perpendicularly separated from the hinge with which the driving source and the rotary link are connected.
