Claims

[Scope of utility model registration request]

a cylinder having a storage chamber for storing a liquid; a piston rod member that divides the storage chamber into an upper chamber and a lower chamber, is slidable up and down within the storage chamber, and has a communication hole that communicates the upper chamber and the lower chamber; an adjusting means for adjusting the flow rate of the liquid passing through the communicating hole, and the adjusting means adjusts the flow rate of the liquid passing through the communicating hole when the vehicle is running to alleviate shocks applied to the vehicle. An opening/closing means is provided to open and close the hole, and when the vehicle is stopped, the opening/closing means closes the communication hole to stop the flow of liquid and fix the piston/rod member to the cylinder, thereby preventing the piston/rod member from sliding up and down. A shock absorber that is characterized by preventing vehicle resonance.
