Abstract:
PROBLEM TO BE SOLVED: To provide an appropriate brake function to a wheel having an inner-and-outer-rings-separated structure including two inner rings.SOLUTION: A wheel is configured: to arrange inner rings 2 in an outer ring 1 with a radial gap between the outer ring 1 and the inner rings to allow the inner rings to play within a predetermined range in directions including a radial direction; to be provided with a shaft hole at a shaft center of the inner ring 2, so that grounding the outer ring 1 causes the inner rings 2 to internally contact with the eccentric outer ring 1, as well as to be able to change internal contact positions thereof while rolling on an internal surface 10 of the outer ring 1, wherein an internal ring 5 is integrally formed on the internal surface of the outer ring 1 inside the outer ring 1, and the inner rings 2, 2 in a pair are arranged to be able to move closer to or away from each other in the shaft center m direction across the internal ring 5 to constitute a double-ring structure. Thus, the wheel is configured to press the inner rings 2 against the internal ring 5 to integrate the inner rings with the internal ring 5 and the outer ring 1, when an external force to narrow the interval between the inner rings 2, 2 is applied.SELECTED DRAWING: Figure 5
