A first space Sa is formed between the radiator grille 3 and the radiator 5. The radiator 5 is supported by the radiator core upper 54 and the radiator core lower 55 extended in a car width direction above and under it. The hood 2 is supported by a hood support 8 extended in the car width direction above the radiator core upper 54. Between the radiator core upper 54 and the hood support 8, a second space S communicated with the first space Sa is formed. An upper air guide 9 is provided to be obliquely extended from an upper part of the radiator grille 3 toward an upper part of the radiator 5 to part the first space Sa.
