ABSTRACT:
A road surface condition changing apparatus which increases a coefficient of friction between a wheel of a vehicle and a road surface without using any consumable materials. A cylinder member is provided in front of the wheel of the vehicle. The cylinder member is rotatable about a rotational axis corresponding to a longitudinal center of the cylinder member. The cylinder member is pressed against a road surface so as to change a road surface condition while being rotated. A support mechanism supports the cylinder member so that the rotational axis of the cylinder member is parallel to the road surface and is inclined with respect to the rotational axis of the wheel. Protrusions, brushes or a water absorbing material may be provided on an outer surface of the cylinder member.
