Abstract

A skate includes a ring-shaped wheel rim (1), in inner side of which a ring-shaped track (5) is provided and extends along the circumferential direction of the wheel rim; a wheel carrier provided in the inner side of the wheel rim; rollers (41, 42) located on the wheel carrier and rolling on the ring-shaped track (5); a pedal (3) provided on the wheel carrier. So the skate with such structure can decrease the height of the pedal, and eliminate the limit that the diameter of the wheel rim cannot be increased because of the limit of torque effected on the feet. Therefore, the diameter of the wheel rim of the skate can be much larger than the diameter of the sliding wheel of the prior skate, and thus the skate has the stronger performance of crossing the vertical wall.
