Claims

[Scope of utility model registration request]

(1) The lower part of the hollow piston is slidably inserted into the cylinder via the piston, and the piston has a pressure port and an extension port, and a pressure leaf valve is installed at the end of the pressure port and the end of the extension port. An extension leaf valve is provided that can be opened and closed freely, two holes are provided in the piston rond in two stages, a check valve with a fixed orifice is provided at the bottom of the piston rond that can be opened and closed freely, and a hollow rotary valve is installed in the piston rond. In the shock absorber, a valve is rotatably inserted, and the rotary valve is provided with an orifice that is selectively opened and closed with the hole in the piston rond. A shock absorber damping force adjustment device in which the valve is provided with one or more orifices that are selectively opened and closed with this hole.

(2) The damping force adjusting device for a shock absorber according to claim 1, wherein the hole in the piston rond communicates with the lower liquid chamber through a hole provided in the piston.

(3) The shock absorber damping force adjusting device according to claim 1, which is capable of arbitrarily adjusting the rebound damping force when soft.
