Title:
FLUID PRESSURE AND CRAMP DEVICE
Document Type and Number:
Japanese Patent JP2000027811
Kind Code:
A
Abstract:

To hold a determined thrust without sharply reducing the thrust of a piston rod by sliding even if the piston rod is dislocated a little.

A piston 9 driven by the action of a fluid pressure is arranged in a cylinder main body 3, and a piston rod 2 projected to the outside of the cylinder main body 3 is arranged in the piston 9. The piston rod 2 is held so as to restrict its driving by a brake unit 4. In a condition in which the piston rod 2 is held by the brake unit 4, a gap is generated on a holding position of the piston rod 2 when the fluid pressure gets to a non-action condition. Even if such positioning slide is generate, the thrust of the piston 2 is kept by an auxiliary rod 24 and a coil spring 42 arranged on the piston rod 2.
