description PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer composition for air bag housing cover excellent in appearance, low temperature impact resistance and tensile break elongation.SOLUTION: A thermoplastic elastomer composition contains at least the following components (A) to (D). Component (A): 20-40 pts.mass of a polypropylene-based resin. Component (B): 20-50 pts.mass of a linear low density polyethylene-based resin having a melt flow rate measured at 190°C and a load of 21.2 N according to JIS K 7210 of 10-30 g/10 min. Component (C): 6-20 pts.mass of an ethylene/1-butene copolymer rubber. Component (D): 6-20 pts.mass of an ethylene/1-octene copolymer rubber.SELECTED DRAWING: None 【課題】外観、低温耐衝撃性及び引張破壊伸びに優れたエアバッグ収納カバー用熱可塑性エラストマー組成物を提供する。【解決手段】少なくとも下記成分（Ａ）〜（Ｄ）を含有する熱可塑性エラストマー組成物。成分（Ａ）：ポリプロピレン系樹脂２０〜４０質量部、成分（Ｂ）：ＪＩＳＫ７２１０に準拠して１９０℃、２１．２Ｎ荷重にて測定されたメルトフローレートが１０〜３０ｇ／１０分の線状低密度ポリエチレン系樹脂２０〜５０質量部、成分（Ｃ）：エチレン・１−ブテン共重合体ゴム６〜２０質量部、成分（Ｄ）：エチレン・１−オクテン共重合体ゴム６〜２０質量部【選択図】なし
