Abstract: The rebound spring structure includes: a rebound spring; a lower rebound collar configured to hold an end on one side of the rebound spring; and an upper rebound collar configured to hold an end on the other side of the rebound spring, the rebound spring structure being positioned around a rod configured to move relative to a cylinder. The lower rebound collar is held by a piston rod. The upper rebound collar is movably fitted to the piston rod. The upper rebound collar includes a recess on an upper disk part configured to restrict movement of the rebound spring to the other side, the recess being configured to facilitate movement of the upper rebound collar in a circumferential direction of the piston rod.
