るガススプリング。[Claims for Utility Model Registration] A cylinder filled with pressurized gas and lubricating oil is defined by a slidable piston so as to be able to communicate with a first chamber on the top side and a second chamber on the piston rod side, In the gas spring, an oil chamber for storing the lubricating oil is formed between a rod guide at the end of the cylinder through which the piston rod protrudes in a gas-liquid tight manner and an intermediate guide member having a through hole through which the piston rod passes. The member includes the oil chamber and the second
A communication hole communicating with the chamber and a valve member capable of closing the communication hole only when the second chamber is compressed are provided, and the intermediate guide member is provided in the piston rod when the second chamber is in the most compressed state. A gas spring characterized by having a narrow diameter portion that forms a gap between the gas spring and the through hole.
