PROBLEM TO BE SOLVED: To glide on a snow plain using natural force by a play apparatus proposed for gliding on the snow plain of a field not under cultivation or vacant land only by wind force in view of having no activity that can contribute to the sound upbringing of people without any sport enjoyable as amusement in a snow district unless going to a skiing ground with a lifting facility. SOLUTION: A sail that receives wind, and a wide ski board (known as a snowboard) are connected by a universal joint. Gliding on the snow by wind force is attained by riding on the ski board and handling the sail.
