A reflecting mirror 9 for a warning light has first to fourth reflecting surfaces 41 to 44. The first and second reflecting surfaces 41 and 42 surround a light source 8, and respectively reflect light from the light source 8 in first and second irradiation directions D1 and D2. A third reflecting surface 43 is arranged inside the second reflecting surface 42, and reflects the light from the light source 8 in the first irradiation direction D1 while having slits 60 for passing the light in the second irradiation direction D2 formed thereon. A fourth reflecting surface 44 is arranged inside the first reflecting surface 41, and reflects the light from the light source 8 in the second irradiation direction D2 while having slits 69 for passing the light in the first irradiation direction D1 formed thereon. The light reflected by the third reflecting surface 43 is irradiated in the fist irradiation direction D1 after passing through the slits 69. The light reflected by the fourth reflecting surface 44 is irradiated in the second irradiation direction D2 after passing through the slits 60. |
