Abstract:
According to the present invention, a multiple-use piston (7) has a two-split structure of a piston body (22) and a piston cap (23), and a one-direction rotation restriction unit (40) is disposed which: restricts a relative rotation of the piston body (22) with respect to the piston cap (23) in the forward rotation direction when a spindle (82) is rotationally driven in the forward rotation direction between the piston body (22) and the piston cap (23); and allows the relative rotation of the piston body (22) with respect to the piston cap (23) in the reverse rotation direction when the spindle (82) is rotationally driven in the reverse rotation direction.
