<p>The omni-directional wheel includes first support parts (20) and second support parts (21) which support large-diameter rollers (30) and (31) and small-diameter rollers (40) and (41). Each of the first support parts (20) is disposed at a position where the first support part is held between a pair of the large-diameter rollers (30) and (31), while each of the second support parts (21) is disposed at a position where the second support part is held between a pair of the small-diameter rollers (40) and (41). The large-diameter rollers (30) and (31) and the small-diameter rollers (40) and (41) 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 (40, 41) partially inserted in the recessed portions (30c, 31c) of the large-diameter rollers (30, 31).</p> |
