To facilitate gliding with a preferable curve and well-balanced in both right and left directions.

This gliding tool is provided with a steering shaft 20 which is provided on a main body part 10, and put in the vertically tilting state to the axis 11 parallel to the gliding surface of the main body part 10 and extending in the longitudinal direction, a journal part 25 where the steering shaft 20 is journalled to the wheel unit 30 so that when the wheel unit 30 corresponding to the steering shaft 20 is directed in the longitudinal direction when a boarding surface 12 is positioned in parallel to the gliding surface, and oscillated in the lateral direction when the boarding surface 12 is turned in the lateral direction centering round the axis 11 and inclined, and an oscillation non-symmetrical means for making the oscillating operation in the lateral direction of the wheel unit 30 assymmetrical.
