PROBLEM TO BE SOLVED: To obtain a weather strip for automobiles which has a very small permanent compression set, exhibits oil resistance and scratch resistance and gives good external appearances. SOLUTION: The weather strip for automobiles is obtained by electron beam irradiation of a foam mainly composed of a thermoplastic elastomer composition which comprises an ethylene-α-olefin copolymer (1) forming a matrix, and a crystalline polyethylene resin (2) and a conjugated diene block copolymer (3) forming a three-dimensional network structure in the matrix.
