To solve the inconvenience that a three-dimensional sledge straightly slides down a slope and can not cope with the speed and the disadvantages that a user just sits on it and slides so that the movement of the body and the operation of an implement are simple, dynamism and power are missing and interest does not continue.

Small-sized ski boards are incorporated on both sides of the top part of a three-dimensional sledge body, and by increasing and decreasing loads onto the small-sized ski boards, the raising degree of an inner edge and the opening size of a tail in linkage with an operation function part on the inner side, one-side braking and both-side simultaneous braking are provided. Also, a stable foothold where the feet can be freely placed, deflection and a side curve are possessed on the bottom surface of the three-dimensional sledge body, the deflection and the side curve are merged, thereby the loading on the three-dimensional sledge and edging for turning an outer edge on the outer side of both sides to the inner edge are performed, and thus the entire three-dimensional sledge performs rotating movement.
