Abstract
A cylinder which can precisely feed a piston rodinto three different positions. The cylinder includes a spring receiving memberwhich is placed coaxially with the piston rod in a piston room. Movement of the pistonis limited by one end of the piston room and a stopperformed on the piston rod which prevents the piston from moving in the opposite direction. A first spring memberis disposed in the cylinder tubeto separate the spring receiving member from the piston. A hollowis formed on the periphery of the piston rod at a further position from the piston than the stopper and a stop pinin the cylinder tubewhich is biased in the direction of the hollow by a second spring memberengages with the hollow. A load port utilizes the cylinder for a production system.
