Abstract
The omni-directional wheel includes first support parts and second support parts which support large-diameter rollers and small-diameter rollers. Each of the first support parts is disposed at a position where the first support part is held between a pair of the large-diameter rollers, while each of the second support parts is disposed at a position where the second support part is held between a pair of the small-diameter rollers. The large-diameter rollers and the small-diameter rollers are disposed such that their outlines are arranged on a single circumference, with a part of the small diameter-side end face of the small-diameter rollers partially inserted in the recessed portions of the large-diameter rollers.
