る長さ調整式ガススプリング。 A piston with a piston rod is housed in the inner cylinder, and the piston rod divides the chamber into a first pressure chamber through which the piston rod penetrates and a second pressure chamber through which the piston rod does not penetrate. In a gas spring having a valve that can communicate or shut off chambers, when the gas spring is in the first pressure chamber and has a predetermined length or more, it is biased in a direction away from the piston, and when the length is less than a predetermined length, the piston is biased away from the piston. 1. A length-adjustable gas spring, characterized in that a free piston is provided which is biased in a direction and moves to block the passage.
