GREEN SKI

PURPOSE:To play the role of steering by a infinite track part and to obtain a green ski to be easily turned by providing the degree of freedom for a turn in a plane direction for more than one infinite track part at least. CONSTITUTION:In the green ski equipped with the two infinite track parts, an infinite track part 1 and a plate-shaped member 5 are fitted by using a stainless steel plate 4. On the stainless steel plate 4, a hole is bored for inserting a turning shaft 13 and the turning shaft 13 is inserted to the hole. Two bearings 12 are inserted to the turning shaft 13 with the stainless steel plate 4 between and on an upper part side, a frame 3 of the infinite track part 1 is fastened by an insertion stopper 11. Then, the lower side is directly held to the bearing 12 and fastened by a nut 11. In such a state, the plate-shaped member 5 and the infinite track part 1 are linked. In order to prevent the infinite track part 1, the turning shaft 13 is inserted to the frame 3 on the lower side of the infinite track part 1. Then, the turning shaft 13 is sandwiched from the both sides and fastened by the stopper nut 11. Thus, since structure is obtained so that the plate-shaped member 5 and the infinite track part 1 can be linked, the infinite track part 1 can obtain the degree of freedom in a turning direction to the plate-shaped member 5 with the turning shaft 13 as a center.
