PROBLEM TO BE SOLVED: To prevent the leak wave of light source lamp form making noise of radio and the like for the air cleaner of having the light source lamp that excites photocatalyst. SOLUTION: An air cleaner 1, which is set on a rear tray 4, is adjacent to an antenna wire 6, which is put on a rear window 5. The wave leakage prevention member 11 is set on to cross the air course in the casing 8 of air cleaner 1. The wave leakage prevention member 11 has a wire netting, which has a high transmission-hole density and a lattice frame, which has a low transmission-hole density. It prevents securely the wave leakage that covers wide frequency range. The lattice frame has a strength and supports the photocatalyst support body 9A through the wire netting to prevent the deformation.
