Abstract
A crash can is made of aluminum-alloy casting and provided between a side frame extending in a vehicle longitudinal direction at a side portion of a vehicle and an end portion of a bumper reinforcement extending in a vehicle width direction. The crash can comprises a hollow tube portion extending in the vehicle longitudinal direction and having a cross-shaped section. At least one of an outwardly-projecting corner portion and an inwardly-projecting corner portion of the tube portion is formed by a groove such that a thickness thereof is thinner than that of the other portion of the tube portion. Accordingly, an impact which a vehicle body or a passenger may receive in a vehicle collision can be reduced by the crash can.
