A bumper assembly of a vehicle is provided to decrease wound of a passenger by alleviating impact through multi-stages although impact energy higher than a constant lever is applied to an aluminum bumper beam. A bumper assembly of a vehicle includes a bumper beam(100) installed at a rear and a front sides of the vehicle to alleviate impact force applied to the vehicle. The bumper beam comprises a first shock-absorbing rib part(110) supported by a first buffer rib(111) and formed on a front end in which impact is generated, and a second shock-absorbing rib part(120) supported by a second buffer rib(121), and connected the rear side of the first shock-absorbing rib part around a dividing rib(130).
