Abstract
An automotive crashworthiness energy absorption part provided at a front part or a rear part of an automotive body and absorbing crashworthiness energy by undergoing axial crush when receiving input of a crashworthiness load from a front or a rear of the automotive body includes: a tubular member configured to absorb crashworthiness energy by undergoing axial crush, the tubular member including a top portion and side wall portions continuous with the top portion; and resin coated or patched on first outer surfaces including at least outer surfaces of the top portion and the side wall portions of the tubular member. The coated or patched resin has a thickness of 8 mm or less after being heated, forms at least part of a peripheral wall portion of a closed cross section space, and is bonded to the first outer surfaces with an adhesive strength of 10 MPa or more.
