PROBLEM TO BE SOLVED: To provide a vehicle braking auxiliary device capable of being easily posteriorly mounted also to an already running vehicle. SOLUTION: A frictional resistance increasing means 3 is set in a type where a slip preventing material 1 is distributed near the ground section of a tire 2 to increase the frictional resistance between the tire 2 and the road surface. A force sensor for operating the means is set as a treading force sensor 5 to which a treading force of a driver B strongly acts at a sudden braking time of a braking device. Thus, the frictional resistance increasing means 3 can be easily mounted without using a firm reinforcing member. The treading force sensor 5 for operating it can be also mounted without changing a piping system or a control system of the braking device, and can be easily posteriorly mounted also to the already running vehicle A.
