A steering mechanism is mainly comprised of an upper and a lower axle seat, in which the upper axle seat and the lower axle seat are provided for receiving an upper axle and a lower axle respectively. The upper and the lower seats are combined together by pivotally jointing each other with a respective inverted U-shaped and a U-shaped pivot-joint ends, where a universal joint having two ends thereof coupled with the upper and the lower axles is arranged in a space enclosed by the pivot-joint ends, so that a diversion may be made by taking the upper axle as a rotation center irrespective of the forward rake or backward rake of the upper axle seat.
