Abstract
A shock absorber interposed in parallel with a suspension spring between a vehicle wheel and a vehicle body of a vehicle comprises a main piston () partitioning a cylinder () into a first operating chamber (R) and a second operating chamber (R), and connected to a piston rod (). The first operating chamber (R) and the second operating chamber (R) are connected by a laminated leaf valve (V, V) under a first flow resistance. A passage () connects one of the pressure chambers (RA, RB) partitioned by a free piston () and the first operating chamber (R) under a second flow resistance. A passage () connects the other of the pressure chambers (RA, RB) and the second operating chamber (R) under a third flow resistance. The shock absorber displays stable damping force characteristics as a result of a spring (S) supporting the free piston () in a predetermined neutral position.
