A driving mechanism of a steering wheel includes a sector gear driven by a gear shaft to rotate on a gear shaft linked together with the sector gear, and a displacement plate having one end fixed with the gear plate shaft and another end pivotally connected with two directional pull rods that are further connected with a directional joint of two front wheels respectively. When a steering wheel is turned left or right, the gear shaft is to be rotated to simultaneously drive the sector gear and the gear shaft to turn around, so that the displacement plate, the directional pull rods, the directional joints and the front wheels can be concurrently driven to undertake an angular displacement for changing a car's direction. Thus, the driving mechanism of the invention has a relatively small size, with cost lowered as well.
