SOLUTION: This wheel includes a plurality of rollers having center holes, a ring inserted in the center hole of the roller and functioning as an axle of the roller, and a wheel body, to which the ring is mounted. One part of the ring made of an elastic material is cut to form a slit, and the roller is inserted through the slit. A center hole or a shaft to be connected with a drive source is processed on the center of the wheel body, and a concave part corresponding to a plurality of rollers and circumferential grooves corresponding to the rings are formed on an outer periphery.
