Fluid pressure apparatus
A fluid pressure apparatus includes a piston, and a packing provided on an outer circumference of the piston. The packing includes a support ring made of a low-friction material, and a ring-shaped seal member mounted to the support ring. When at least a certain amount of transverse load acts on the piston, an outer circumferential surface of the support ring abuts against an inner circumferential surface of the slide hole, whereby the piston is prevented from contacting with the inner circumferential surface of the slide hole.
