PURPOSE: A bumper back beam for a vehicle is provided to successively absorb impact load although impact load is given to the bumper back beam several times while the vehicle runs, by absorbing impact load while a lower back beam is deformed and widely dispersing the impact load through side members. CONSTITUTION: A bumper back beam(100) for a vehicle is fused all over a bumper mounting bracket(200) the lower part of which is fused on the front end parts of side members(300). The bumper back beam is divided into an upper back beam(110) and a lower back beam(120). The upper back beam and the lower back beam are each fused on the upper and lower parts of the bumper mounting bracket. The upper back beam and the lower back beam are each fused on the bumper mounting bracket in a state of reducing the clearance.
