Abstract
A gas spring comprising a cylinder body filled with compressed gas and an upright rod passing through a rod side end wall member of the cylinder body. By supporting a main shaft unit with the gas spring, the load on a vertical displacement mechanism is reduced. A pair of upper and lower ring-shaped seal members, which seal between the rod end wall member and the rod, are provided inside the rod wall member. Ring-shaped oil filling chambers are formed in between the ring-shaped seal members and between the rod end wall member and the rod. An oil filling mechanism fills the oil filling chambers with lubrication oil.
