    摘要: The present invention provides an energy absorbing member for a vehicle, capable of maintaining a desired energy absorbing performance in a wide range from the high temperature to the low temperature. The energy absorbing member for a vehicle 1 is for absorbing the impact from the inside or the outside by being disposed inside the vehicle constituent member. The energy absorbing member for a vehicle 1 is formed integrally by blow molding of thermoplastics. The energy absorbing member for a vehicle 1 having a hollow part comprises a pair of recessed ribs 5 and 6 formed by denting a first wall 3 toward a facing second 4 wall and denting the second wall 4 toward the facing first wall 3 with the top end parts welded with each other. The top end parts of the recessed ribs 5 and 6 are bonded so as to provide a welded surface 7. The energy absorbing member for a vehicle 1 is made of thermoplastics produced by adding 35 to 75 wt% of an amorphous resin to a polyolefin based resin, or thermoplastics produced by adding an olefin based elastomer, or the like to a polyolefin based resin.
