PROBLEM TO BE SOLVED: To provide a signal device capable of suppressing power consumption while preventing reduction in visibility due to snow accretion.SOLUTION: A signal device 100 includes: a light source plate 110 having a light source 111 for a signal disposed at a rear face side of the light source plate; and a reflector plate 120 for reflecting toward emission light Lfrom the light source 111 for the signal disposed behind the light source plate 110. A user of the signal device visually recognizes the light source 111 for the signal by reflected light Lfrom the reflector plate 120. It is preferable to provide, on the reflector plate 120, snow accretion preventing means 150 for preventing snow accretion to the reflector plate 120.SELECTED DRAWING: Figure 1 |
