ーバ。[Claims for Utility Model Registration] (1) A piston having a throttle hole penetrated through the insertion end of the piston rod inserted into a cylinder filled with fluid is installed so as to be relatively movable in the axial direction of the piston rod. A shock absorber characterized in that a stopper member is provided on the outer periphery of the piston so as to sandwich the piston and face each other to restrict the range of relative movement of the piston, and at least one of the stopper members is movable to make the distance between the two pistons variable. (2) One of the stopper members is formed into a cylindrical body,
This is screwed onto the outer periphery of the piston rod so that one end faces the other stopper member, and the other end projects outside the cylinder and the protrusion is rotated to vary the opposing distance. The shock absorber according to item 1. (3) Request for registration of a utility model in which one of the stopper members is made of a bimorph piezoelectric material or a bimetallic body that deforms in the direction opposite to the other stopper member when energized, and the opposing distance is variable by energization from outside the cylinder. The shock absorber according to item 1.
