PROBLEM TO BE SOLVED: To provide an improved shock absorber for decelerating and moderating the movement of a rod-like member with respect to a housing near either end of its stroke. SOLUTION: The bidirectional self-contained stroke end shock absorber 20 comprises the housing 21; the rod 22 movable relative to the housing; a single fluid-filled variable volume chamber 23 communicating with a fluid sump 24 through an orifice 65; and a lost motion mechanism for selectively reducing the volume of the variable volume chamber near each end of the stroke of the rod-like member. The lost motion mechanism forcibly feeds a fluid from the variable volume chamber through the orifice to decelerate the movement of the rod-like member at the end of the stroke.
