ABSTRACT:
The wheels for roller skates and the like in accordance with the present invention comprise wheel bodies which have sockets provided at right and left ends of the wheel bodies and communicated through center holes with a diameter smaller than that of the sockets, two ball bearings mounted on the wheel bodies and elastic pipes inserted into the center holes, wherein two ball bearings are made with a construction in which steel balls are provided between the inner ring provided with a flange on its outer periphery and the outer ring provided with a flange on its inner periphery and these flanges are concentrically fitted in opposed position and mounted onto the outer peripheries of the flanges of the outer and inner rings, and the ends of a hub of the inner ring is fitted into the right and left sockets of the wheel bodies while being kept contact with the ends of the elastic pipes, thereby the wheels are suited to prevent backlash due to wear and tear of steel balls and outer and inner rings resulting from any suddenly varying excessive and heavy load such as, for example, a force in the direction of thrust.
