Abstract
Variation in steering force is reduced by providing side edges attached to the right and the left side surfaces of a steering ski. The side edges have a continuously curved lower surface. A vertical plane including the axis of a pivot shaft crosses a middle portion of each side edge. Dislocation of contact centers from a pivot point, and the distances between the pivot point and the contact centers are small when the steering ski swings on the pivot shaft.
