<p>PROBLEM TO BE SOLVED: To provide a grass ski capable of facilitating a parallel operation of two grass ski legs generally made so as to be symmetrical in a lateral direction and in forward and backward directions, and improving sliding performance and operational performance.SOLUTION: A grass ski 1 includes: an annular rail 2; a base 3 which holds the rail 2 in a shaping manner, and to which a step base 3a is fitted; a plurality of elements 4 arranged on the rail 2 which support a plurality of rollers 7; a belt 5 which holds the elements 4 at constant intervals; and a plurality of plates 6 which fix the elements 4 and the belt 5, and is used as a right and left pair. The height of the right and left inside end is made greater than the height of the outside end for the direction of travel of the grass skis 1, and the height of the inside end of the respective grass skis 1 is made greater than the height of the outside end. The step base 3a is arranged behind the center in the forward and backward directions of the grass ski 1.</p> |
