Claims

[Scope of utility model registration request]

(1) It has a cylinder, a piston provided slidably in the cylinder, and a piston rod whose one end is connected to the piston and whose other end is led out of the cylinder, and the circumference of the piston rod is The surface is formed with opposing convex inclined walls and a rising step wall, and the inclined wall has a lock having an approximately V-shaped cross section and an elastic ring having an elastic force in the direction of diameter expansion. A member is fitted into the cylinder, and an actuating member is provided that protrudes inward in the radial direction of the cylinder and includes a retaining portion that can come into contact with one side of the locking member and a retaining release portion that swings the locking member. , a locking position where one side of the locking member abuts the engaging portion and the locking member is sandwiched between the engaging portion and the stepped wall, thereby restricting movement of the piston rod in one direction; By moving the piston rod in the other direction, the locking member is swung by the disengaging member, and the locking member can be displaced between an unlocked position in which the side surface does not come into contact with the engaging portion. A gas spring characterized by the following.

(2) The locking member is an elastic ring made of metal having a notch in the radial direction.
Gas spring described in section 1).

(3) The gas spring according to claim (1), wherein the locking member is formed by forming a rubber material into an annular shape.

(4) The gas spring according to claim (1), wherein the face part is formed by bending the tip of a cylindrical elastic body inward.
