Claims

[Claims for Utility Model Registration] 1. A system comprising a fluid introduction path from the outside of the cylinder through the inside of the piston rond to the sliding surface of the piston, and a fluid discharge path from the sliding surface to the outside of the cylinder through the inside of the piston rond. A low-friction type fluid pressure cylinder configured such that the static pressure of the fluid flowing from the fluid introduction path to the fluid discharge path is applied to the interface with the cylinder tube. 2. The low-friction type fluid pressure cylinder according to claim 1, which is provided with a fluid introduction path and a fluid discharge path that apply static pressure of fluid to the interface between the piston rod and the bushing of the cylinder.
