Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cover for housing a non-destructive air bag which is composed of an olefin based thermoplastic elastomer composition and has mechanical properties such as moderate rigidity (flexibility) and cold impact resistance and, low surface gloss and excellent mold release characteristics and dimension stability as well. SOLUTION: The cover for housing a non-destructive air bag is composed of an olefin based thermoplastic elastomer composition comprising (A) 30-70 wt.% olefin based thermoplastic elastomer, (B) 25-45 wt.% propylene based polymer, and (C) 5-25 wt.% ethylene/α-olefin copolymer (provided that wt.% of each component is based on 100 wt.% sum of these three components) and having a flexural modulus of 500-1,000 MPa.
