Claims

[Scope of utility model registration request]

(1) A piston is slidably inserted into a cylinder to define the inside of the cylinder in a regular character, a piston rod extending outside the cylinder is attached to the piston, and one of the regular characters is attached to the piston rod. forming an inner chamber that communicates with the other chamber; first and second orifices that communicate between the inner chamber and the other chamber of the orthograph; forming first and second orifices in the inner chamber; A movable wall that selectively narrows the first and second orifices is slidably fitted, an operating rod is connected to the movable wall, and the first and second orifices are connected to the outer peripheral side of the piston rod. A damping force adjustable shock absorber comprising a check valve that is closed when the piston rod is extended and opened when the piston rod is shortened.

(2) Utility Model Registration Scope of Claim 1 In the first orifice, the first orifice has a different opening area. A damping force adjustable shock absorber comprising a plurality of orifices, the second orifice comprising a plurality of orifices having different opening areas.

(3) Utility Model Registration A damping force adjustable shock absorber according to claim 2, characterized in that the plurality of orifices are arranged in a circumferential direction of a piston rod.
