とするガススプリング。 A piston with a non-magnetic piston rod is installed inside the inner cylinder, and the first piston rod is penetrated by the piston rod.
In a gas spring that is divided into a pressure chamber and a non-penetrating second pressure chamber and has a communication path that communicates the first and second pressure chambers, a magnet is provided at a predetermined position of the piston rod, and the first pressure chamber is divided into a pressure chamber and a non-penetrating second pressure chamber. A free piston made of a magnetic material is disposed in the chamber, which is biased in a direction away from the piston, and when the gas spring falls below a predetermined length, is attracted by the magnet and moves to block the passage. gas spring.
