When a horizontal shaft and a piston are caused to travel to a first side with a gear coupling engaging, the revolution of the piston is designed to be restricted by meshing a spur gear with an internal gear fixed to a main body of a horizontal swivel part. On the other hand, when the horizontal shaft and the piston are caused to travel to a second side and the gear coupling thus disengages, the horizontal shaft and the piston are designed to be revolved in an integrated manner by meshing spur gears respectively with other spur gears. When the horizontal shaft and the piston travel from the first side to the second side, the spur gear is designed to be spaced away from the internal gear after the spur gear meshes with the spur gear.

In a case where the load is not smaller than the predetermined value, the positioning is not completed even when it is determined that the movable body is moved to the position supposed to be the target position, then the movable body is moved to a retry starting position different from the position supposed to be the target position, subsequently a retry operation is performed for moving the movable body from the retry starting position to the position supposed to be the target position, and consequently the positioning is completed when the load becomes smaller than the predetermined value after the retry operation is performed for a predetermined number of times.
