Abstract

PURPOSE: To protect a weak part or the like being supplied with a fluid, from damage, by using a permanent magnet to connect a piston and a piston rod to each other and by disconnecting the piston and the piston rod from each other when an external force stronger than a prescribed level acts to the rod, so that only the rod runs away.
CONSTITUTION: An annular permanent magnet 8 is provided in a piston 7. A piston rod 6 is made of a magnetic substance to exert a magnetic attractive force between the piston 7 and the piston rod 6. The magnetic attractive force is set stronger than a force which is caused by supplied fluid pressure necessary to actuate a driven part through the medium of the piston rod 6. When an external force stronger than the magnetic attractive force acts to the piston rod 6, the piston 7 is held in its position by the fluid pressure and only the piston rod 6 runs away.
