Claims

[Scope of utility model registration request]

(1) A piston rod that penetrates the sealed end of the cylinder and enters and exits is installed in a cylinder that is sealed at both ends, and a piston that separates the inside of the cylinder into two oil chambers is fixed to the piston rod end. Additionally, a free stone is provided in the cylinder to separate one of the oil chambers from a gas chamber filled with high-pressure gas, and the piston is attached to the other side of the oil chamber in a direction opposed to the gas pressure of the gas chamber. Stay Danno is characterized by a spring that acts as a spring.

(2) The stay damper according to claim 1, wherein the piston is provided with a damping force generating means.

(3) The stay damper according to claim 1, wherein the spring is a coil spring.
