閉されることを特徴とするガススプリング。 The piston, which is reciprocably housed in a cylinder filled with gas and defines the inside of the cylinder into two chambers, has a cylindrical part extending toward one gas chamber, and the inside of this cylindrical part. A communication hole is formed that communicates the chamber with the other gas chamber, and an orifice that is located on the outer peripheral side of the cylindrical portion and communicates between the one gas chamber and the other gas chamber is formed. A gas spring characterized in that a piston rod that is removably inserted into the cylinder is engaged with the cylindrical portion so as to be relatively movable over a certain distance, and the communicating hole is opened and closed at the tip of the piston rod.
