PURPOSE:To prevent the production of chips from the stopper or tube by putting the stopper in the tube in the playing state, by sliding it in assembling them and by matching the ringwise concave of the stopper with the ringwise convex of the tube. CONSTITUTION:After completion of a fixed arrangement of elements of the gas spring, gas is pressed in the tube 1, the piston and stopper 6 are pulled up at the same time. At this time, since the stopper is playingly put in the tube, it is not contacted with the inner surface of the tube and shaves are not produced. When the stopper is further pulled up, the concave 6a of stopper is matched with the convex 1a of the tube 1 to make the stopper static. |
