摘要： A roller skate includes three or more wheels rotatably supported in the lower portion. The front wheel is disengaged from the ground surface when the middle wheel and the rear wheel are in contact with the ground surface, and the rear wheel is disengaged from the ground surface when the middle wheel and the front wheel are in contact with the ground surface. The rear wheel is coupled to the front wheel so as to be driven by the front wheel when the rear wheel is elevated and is not in contact with the ground surface.
