PURPOSE: To obtain a corrugated sliding way with wider playing methods by providing a rectangular bottom plate with a continuous low corrugated shape.

CONSTITUTION: Whole long side lower edges are fixed to both long side ends of a rectangular bottom plate 3 continuously formed with low corrugated shapes 2 having slowly heaved wave crests 1. Main bodies fitted with handrails made of pipes 5 or the like on the whole long side upper edges of erected band-shaped side plates 4 are obliquely erected and fixed on a frame or the like. When a person slides on the bottom plate 3 from the above, a quick slide on a steep slope and a slow slide on a slow slope are repeated in turn for the descent.
