A kick board using a leverage theory is provided to travel forward by rotating both the front and rear wheels of the kick board by pushing a handle shaft by an arc leverage, thereby providing a kick board having a thrill feeling by enabling a child to put his both feet on foot plates of the kick board and push and pull a handle repetitively by arms. A kick board using a leverage theory comprises the following units. A front wheel(2) in the center of the front of the board(1) and a rear wheel(3) in both sides of a board rear side are rotatably installed. A handle shaft pipe body(4) is rotatably installed in right/left direction to be adjustable with the front wheel at the same time in an upper side of the front wheel. A handle shaft(5) is inclinedly and vertically installed in the handle shaft pipe body. A handle(7) for adjusting direction is horizontally installed by installing knobs(6) in both sides in an upper end of the handle shaft. A hand brake lever(8) for stopping the kick board is installed by breaking the rear wheel in the handle. A plastic material rectangular noise cancellation fixture(12) is fixed in an upper center surface of the board. An upper end of the handle shaft pipe body and a lower end of the handle shaft are coupled by a hinge pin(13). The handle shaft is rotatably installed in the front/back sides from the handle shaft pipe body. A leverage connecting tool(14) is rotatably inserted into the handle shaft. A support ring(15) is slidingly inserted into the handle shaft in the upper/lower portions of the leverage connecting tool.
