The impact absorption mechanism has a columnar impact absorption material 1 made of wood and a bolt 3. The impact absorption material 1 is covered with a covering material 7, and one end thereof is inserted into a tubular portion of the side member 9. The bolt 3 is connected to the side member 9 and presses against the impact absorption material 1 upon collision. An inclined plane 91 which is inclined further away from the impact absorption material 1 as it proceeds to the bumper reinforcement side is arranged on an inner surface of a front end of the side member 9. The inclined plane 91 includes a corner round part 911 arranged on the inner edge of the front end of the side member 9 and a round part 912 arranged in the side member 9 continuously with the corner round part 911.SELECTED DRAWING: Figure 3
