PURPOSE:To enable a beginner to learn the technique of operating ski boards in the intended direction in a short term by providing a function for changing a sliding direction on the ski boards. CONSTITUTION:A shaft 3 and a steering board 8 are fixed to a rotary tail 2 to be integrally rotated. A bottom board 5 is fixed to a ski board 1 and a rotary board 6 is installed thereon rotatably around a rotary-board shaft 4 as the fulcrum. A ski-shoe mounting fixture 7 is fixed to the rotary board 6 and an operating rod 9 is installed on the fixture 7. Slits 8a are provided on both ends of the steering board 8 and the operating rod 9 is inserted into the slit. As the rotary board 6 is rotated counterclockwise by means of a ski shoe, the operating rod 9 rotates the steering board 8 clockwise. Since the shaft 3, rotary tail 2 and steering board 8 are integrally fixed together, the rotation of the steering board 8 rotates the rotary tail 2 in the arrow line direction. That is, the steering board 8 steeringly acts on the rotary tail portion 2 to facilitate the rotation of the ski in the intended leftward direction. |
