Abstract

The invention relates to a gas spring, comprising an external cylinder tube, an internal cylinder unit installed inside the external cylinder tube, and a piston unit and a control device installed inside the internal cylinder unit. The internal cylinder unit includes an internal cylinder seat made of hard plastic and a guide groove forming board, wherein the internal cylinder seat has a cylinder wall defining a channel, the cylinder wall has an external annular face attached to the external cylinder tube, an axially extending assembly groove concaved inward from the external annular face, and two gas guiding holes which are vertically spaced and communicating the assembly groove and the channel, the guide groove forming board is installed on the assembly groove and mutually defines a guide groove communicating the gas guiding holes with a bottom surface of assembly groove. By the combination between the internal cylinder seat and the guide groove forming board, the guide groove can be easily formed, so as to facilitate the manufacturing and assembling of internal cylinder.
