Abstract
A shock absorber for a vehicle making use of plastic deformation. The absorber is mounted between a bumper and the frame of the vehicle to transform impact energy applied to the bumper into deformation energy. The absorber comprises a straight tube that can be plastically deformed. A straight tube is partially enlarged or partially reduced to form different diameter tube portions. These tube portions are connected by step formed between the edge of each one. Thus, a multi-diameter stepped tube is formed. The tubes located at the both ends of this multi-diameter stepped tube are connected to the bumper and the frame of the vehicle respectively.
