Wheel having rotating bodies

摘要

A wheel (9) having rotating bodies (10) is disclosed wherein a plurality of rotating bodies (10) are disposed around the wheel (9) and are rotatable in a direction orthogonal to the straight-forward direction of the wheel (9). Each of the rotating bodies (10) is rotatably supported around the axis of rotation across the radial direction around an axle (1). Each of the rotating bodies (10) is formed in a shape forming an arc of an outer circumferential circle of the wheel (9) by a circumferential surface (19) with the diameter of a tip portion (12) of the rotating body (10) being smaller than the diameter of a base end portion (11).
