PURPOSE: To safely transfer an object such as conveying skiers or the like by providing a flexible conveying band which makes a wave motion in a vertical direction with one end serving as the fixed end.

CONSTITUTION: One end of a flexible conveying band 1 like a rubber plate is fixed as a fixed end 2, and also a total unit of this conveying band 1 is supported onto a pair of parallel helical shafts 3, 3, rotated in an equal phase, to make the conveying band 1 repeat a wave motion vertically along a shape of the helical shaft 3 by rotating it. When this motion is considered as the wave motion, a waveform is advanced, and, for instance, a skier 4, when standing in a tilt part of this waveform, advances while sliding toward a tilt surface lower part, but since the waveform is also advanced, when its speed is well adjusted, the skier can advance left as riding on the waveform such as in surfing on the sea. That is, the skier 4 is conveyed to a position upward.
