Abstract
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.
