In a wheel (18) of a moving device (10), an outer wheel (28) is rotatably supported by a pair of inner wheels (26). When the moving device (10) is placed on a movement path (30), a lower end portion of the outer wheel (28) is elastically deformed wholly in a radial direction toward the opposite side to the movement path (30). Accordingly, elastic force of the outer wheel (28) to be prevented from dispersing in the axial direction of the outer wheel (28), and elastic force of the outer wheel (28) can be made to act efficiently toward the side of the movement path (30), thereby enabling cushioning performance by the moving device (10) to be raised.
