Shock absorber (Vibration Damper) ikoreshwa cyane cyane mugucunga ihungabana mugihe impeshyi igarutse nyuma yo gukuramo ihungabana n'ingaruka ziva mumuhanda. Mugihe utwaye umuhanda utameze neza, nubwo ihungabana rikurura amasoko ryungurura umuhanda uva mumuhanda, amasoko azakomeza kwisubiraho noneho imashini ikoreshwa kugirango igenzure isimbuka ryamasoko. Niba icyuma gikurura ibintu cyoroshye cyane, umubiri wimodoka uzaba utangaje, kandi isoko izakora neza kandi irwanya cyane niba bikomeye.
