バ。[Claims for Utility Model Registration] A cylinder, a piston that is slidable within the cylinder, an upper piston chamber and a lower piston chamber separated by the piston, and a communication passage that communicates between the upper and lower piston chambers; A working fluid is contained in the piston upper chamber, the piston lower chamber, and the communication passage,
A shock absorber that damps vibrations applied to the piston by flow resistance of working fluid, comprising: a movable spool that is slidable in the communication path; a fixed member that cooperates with the movable spool to form a variable orifice; A reciprocating member that comes into contact with the movable spool to restrict the sliding of the movable spool; an electrorheological fluid that applies pressure from behind to support the retractable member; and at least a member that applies a voltage to an outlet of a chamber containing the electrorheological fluid. A variable damping force shock absorber comprising a pair of electrodes and a control section that controls a voltage applied to the electrodes.
