PROBLEM TO BE SOLVED: To provide a vehicular slip preventive supporting device capable of effectively cooling a tire face even on a frozen road, a wet road or a dry road, and increasing the friction coefficient of a tire to a road surface when requiring the braking or the like. SOLUTION: The vehicular slip preventive supporting device comprises refrigerant spray units A<SB>1</SB>, A<SB>2</SB>having a container to store refrigerant, and a control circuit 10 to control and drive the units via a driving circuit 11. The refrigerant spray units A<SB>1</SB>, A<SB>2</SB>have the same configuration, discharge refrigerant in a spray can 1 by operating a plunger 6 by an electromagnetic coil 5 of a solenoid 4, spray refrigerant on the tire face from a spray nozzle 8b, and cool the tire face by vaporization of refrigerant deposited on the tire face. The units determine the frozen road, the wet road or the dry road, effectively cool the tire by either of the units A<SB>1</SB>and A<SB>2</SB>when required in braking or the like, and increase the friction coefficientμof the tire.
