Abstract
A stopper cylinder is equipped with a body having a drive unit, a piston mechanism being displaceable along an axial direction in the interior of a tube connected to the body, and a stopper lever connected to the piston mechanism for stopping conveyance of a workpiece. Displacement of the piston mechanism is restricted by an electromagnetic lock mechanism, which is disposed on the body and is excited by supply of electric power. After approaching the workpiece, by releasing a locked state of the electromagnetic lock mechanism, the piston mechanism is displaced to a position facing the workpiece by an elastic force of a spring.
