PURPOSE: A crash box for vehicles is provided to effectively support weight for a center test of the RCAR(Research Council for Automobile Repairs) because a square cross-section is partially applied to a stiffness reinforcing part. CONSTITUTION: A crash box for vehicles(100) is installed on both ends of a bumper beam disposed in a width direction and the crash box absorbs the collision energy of a vehicle crash. The crash box has a hollow heptangular section. One interior angle among corners of the section is at 90 degrees to form a stiffness reinforcing part(R). The stiffness reinforcing part is placed toward the interior of the vehicle. A rigid gusset is located towards the inner side direction [toward the interior side] of the vehicle.
