PROBLEM TO BE SOLVED: To provide a collision energy absorption component for vehicle, capable of improving collision energy absorption effect when a collision load is input from the front or rear of a vehicle body and collision energy is absorbed after axial collapse.SOLUTION: The collision energy absorption component for vehicle is provided on the front or rear of a vehicle body and absorbs collision energy when a collision load is input from the front or rear of the vehicle body, and includes a cylindrical member 3 for absorbing collision energy after axial collapse and resin foam 9 charged into the cylindrical member 3. The cylindrical member 3 includes an opening part 11 for discharging the foam resin 9 to the outside during axial collapse, which is formed in a peripheral wall part.SELECTED DRAWING: Figure 1
