Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain an elastic resin excellent in elastic property causing no permanent set in fatigue in a wide temperature range from a low temperature to a high temperature, and to provide an elastic resin molding, clothing, and to obtain an auxiliary material for clothing. SOLUTION: The elastic resin is a polyurethane comprising, as a polyol component, a copolyether polyol of tetrahydrofuran with a 3-alkyltetrahydrofuran, wherein the molecular weight of a soft segment comprising the copolymer portion of a polyurethane-urea polymer chain of the polyurethane is ≤La defined by an equation in the figure, the polyurethane contains ≤1.7 mol organic diisocyanate compound per 1 mol copolyether polyol and the polyurethane has a hard segment comprising a chain extender of at least one diamino compound (A) selected from unbranched chain aliphatic diamino compounds, symmetric cyclic aliphatic diamino compounds and symmetric aromatic diamino compounds, and the chain extender contains no diamino compound other than the diamino compound (A).
