ABSTRACT:
A shock absorber includes a piston for partitioning the interior of a cylinder into two liquid chambers while affording communication between both liquid chambers through a plurality of ports, and a valve body biased toward the piston for opening and closing the ports. The piston has a ring portion which forms a path in cooperation with the valve body for regulating the amount of liquid flowing from the ports around an outer peripheral edge of the valve body. An effective area of the ports is larger than the maximum effective area of the path.
