Abstract
A shock absorber capable of effectively functioning even in case of emergency or abnormality, significantly reducing the manufacturing cost and highly simplifying the structure. A piston is arranged so as to divide a liquid chamber defined in a casing into two liquid chamber sections and a liquid passage is arranged so as to cause the chamber sections to communicate with each other. Also, a movable guide member is provided in the casing and a spring is interposed between the guide member and a flange of an actuation rod, so that the return spring permits both actuation rod and movable guide member to carry out the return operation. Thus, the shock absorber eliminates arrangement of an accumulator in the shock absorber.
