Abstract
A gas spring has a cylinder body, a rod member internally slidably fitted in the cylinder body, and a gas chamber which is formed inside the cylinder body and filled with compressed gas. The seal members for sealing between the cylinder body and the rod member are disposed at both sides of the gas chamber, while ring members for partitioning the gas chamber are disposed at the end portions of the gas chamber close to the seal members, and accordingly, annular grease chambers for grease between the seal member and the ring member are formed, and it is possible to prevent grease shortage by the grease in the grease chambers.
