PROBLEM TO BE SOLVED: To provide a road illumination device that is immune from contact and ignition failure due to repeated vibrations generated by moving vehicles and wind pressures. SOLUTION: The body 1 of a road illumination device is supported by a straight pole P with a vibration-resistant resilient member 7 arranged between the body 1 and the leading end part of the pole P to absorb the vibrations exerted to the road illumination device. The vibration-resistant member 7 comprises a coil spring 72 for absorbing the longitudinal vibrations along the central axis of the straight pole P, and rubber parts 73 and 74 for absorbing the horizontal vibrations.
