ABSTRACT:
A shock absorber for side sills of a chassis is disclosed. The shock absorber is installed in each side sill of a chassis and effectively absorbs a side impact at the side sill in the event of a side collision of a car, thus effectively reducing impact transmission velocity and preventing the side sill from being badly thrust into the passenger compartment in such a collision. In the shock absorber, a fixed guide pipe penetrates the center of a reinforcing member of a side sill box with both ends of the pipe being projected into inner and outer panels of the side sill box. A retractable damper is movably inserted into the guide pipe at a position inside the outer panel, thus primarily absorbing the side impact. A support member is elastically and movably inserted into the guide pipe at a position inside the inner panel, thus finally absorbing the impact.
