PURPOSE: A kick board is provided to easily change an advancing direction by making the advancing direction changed depending on the center of gravity of a rider, to prevent the falling of the rider, and to easily fold and unfold a vertical support pipe and a handle. CONSTITUTION: Rolling wheels(12,13) are installed on a board(11). A vertical support pipe(14) is installed on the front portion of the board. A handle(15) is combined to the upper portion of the vertical support pipe. The vertical support pipe and the handle are foldably supported on fixed rail plate(16) fixed on both front sides of the board. A cross support bar(17) is installed on the lower front portion of the fixed rail plates. Front portions of a pair of support brackets(18) are inserted to both ends of the cross support bar. Thereafter, the support brackets and the front rolling wheels are rotatably installed on both sides of the cross support bar via a rotating support pin(19). Thus, the support brackets and the front rolling wheel interlock mutually. Therefore, the left and right angle of the front rolling wheels is automatically changed depending on the center of gravity of a rider.
