An omni-directional wheel comprising: a substantially cylindrical hub part provided so as to be rotatable around an axle; a plurality of rollers (30, 31, 40, 41) which have axes extending in a direction intersecting a radial direction of the hub part in a plane perpendicular to the axle, each of the plurality of rollers (30, 31, 40, 41) making an outline which has a curvature equal to a curvature of a circle centered around the axle; a support part (20, 21) which allows the rollers (30, 31, 40, 41) to be mounted so as to be rotatable around the respective axes, the support part (30, 31, 40, 41) supporting the rollers such that the outlines are arranged on a single circumference, the support part (20, 21) having an inner circumferential surface larger in diameter than an outer circumferential surface of the hub part; an elastic member which is held between and in contact between the outer circumferential surface of the hub part and the inner circumferential surface of the support part (20, 21) in the radial direction; a pair of first restriction members (10, 11) which are fixed on one of the hub part and the support part (20, 21) and which are disposed in contact with both end faces of the elastic member (51, 52) in a direction of the axle; and a second restriction member which is fixed on the other one of the hub part and the support part (20, 21) and which is disposed between the pair of first restriction members (10, 11) in the direction of the axle, wherein the elastic member (51, 52) includes a first elastic member which is held between and in contact between one of the first restriction members (10, 11) and the second restriction member in the direction of the axle; and a second elastic member which is held between and in contact between the other first restriction member (10, 11) and the second restriction member in the direction of the axle; characterised in that, the inner circumferential surfaces of the first elastic member and the second elastic member are disposed in contact with the outer circumferential surface of the hub part, and the outer circumferential surfaces of the first elastic member and the second elastic member are disposed in contact with the inner circumferential surface of the support part (20, 21). a substantially cylindrical hub part provided so as to be rotatable around an axle;
