PURPOSE: Two wheel type driving board is provided to learn the sense of equilibrium as well as enjoy a faster speed. CONSTITUTION: In the two wheel type driving board(1), a front wheel(3) and a back wheel(4) having one roller respectively are arranged and assembled in a line, and an axis-mounting bar(2) is assembled and mounted between the front wheel and the back wheel in the center of the bottom surface of the board. The front wheel is mounted on a rotating plate(5) capable of 360 degree rotation for freely performing the direction change of the front wheel. The front wheel connects one end of connector(6) to one side of a wheel mounting bar(5a) of the rotating plate and the other end of the connector to an axis holder(7) formed to the axis-mounting bar. Left and right rotation directions of the front wheel are controlled by forward and backward movements of the connector according to rotation states of the axis holder(7). A control part(10) having a brake lever(17) and a handle(16) is assembled in one side end of the axis holder. The axis holder is rotated by the control of the control part. In the back end of the board, a foot plate(8) having a rubber plate(9) for a brake attached removably on the outer surface of the back wheel is axis-mounted elastically by a spring(8a). A steel wire(18) connects the foot plate and the brake lever mounted to the handle.
