    • PROBLEM TO BE SOLVED: To make it possible to sprinkle a freezing preventive agent to a road surface or the like where freezing or snow accumulation is expected in simple handling at a proper timing. SOLUTION: A freezing preventive agent sprinkle device 1 comprises a sprinkler main body 2, a control device 3, and a cable 4 which connects them electrically. This sprinkler main body 2 opens a sprinkle opening on the front and is provided with an alarming lamp 24 which flashes on and off during sprinkling time. A sprinkling unit is loaded inside, which sprinkles a freezing preventive agent from a hopper which contains the freezing preventive agent and the sprinkling opening 25. A sensor or the like, which measures the temperature of an open air, is loaded on a sensor 31 of the control device 3 while the control unit of the device is loaded inside. The device 1 is set up on a shoulder of a road where freezing and snow accumulation are expected. This construction makes it possible to sprinkle the freezing preventive agent in manual mode or in automatic mode by means of the control device 3 at a timing where freezing and snow accumulation are expected.
