Abstract
A lubricating oil received in a portion of a lower end side in a cylinder body is reliably supplied to a rod member and a sealing member to reliably lubricate a sliding part between the sealing member and the rod member by use of a pressure change of compressed gas in a gas spring with the rod member disposed in a posture of protruding it upward from a rod-side end wall of the cylinder body. In the lubricating structure of a gas spring, a pair of check valves preventing a back flow of a lubricating oil from the lubricating oil outlet side to the lubricating oil inlet side are provided in series in a lubricating oil passage connecting the lubricating oil inlet and the lubricating oil outlet, and the lubricating oil is introduced from the lubricating oil inlet into the lubricating oil passage and lubricating oil is discharged from the lubricating oil outlet by use of a pressure change of the compressed gas to supply it to the rod member.
