It may be smaller than the pressing force required when moving to the displacement end position in order to transport the. Therefore, the piston 18 can be sufficiently displaced toward the initial position by the pressure of the pressure fluid supplied (exhausted) from the first cylinder chamber 36 to the second cylinder chamber 38.
