PROBLEM TO BE SOLVED: To realize the excellent sensitivity of a radio wave radar device arranged on a backward side of a vehicle body of a front grille body. SOLUTION: In a radiator grille 10, a millimeter wave emitted forward of a vehicle body by a millimeter wave radar device 28 arranged on a backward side of a vehicle body of a radiator grille body 14 transmits through a flat plate part 20 provided on the radiator grille body 14 at the position facing the millimeter wave radar device 28. The flat plate part 20 is arranged so that its thickness direction is along the longitudinal direction of the vehicle body, and the thickness dimension is set to a constant value so as to transmit the millimeter wave of the millimeter wave radar device 28. Thus, the transmission speed of the millimeter wave transmitting the flat plate part 20 can be unified. COPYRIGHT: (C)2008,JPO&INPIT
