PURPOSE: An omnidirectional wheel is provided to prevent a slip between an inner roller and an outer roller, and to prevent tires of the inner roller and the outer roller from being slipped by spotters. CONSTITUTION: An omnidirectional wheel comprises multiple connecting members(C), an inner roller(100), an outer roller(200), spotters(110,210), and tires(120,220). The connecting members are coupled to a hub(H). The inner and outer rollers are formed in order using the connecting members. The spotters are connected to shafts(S) through a bearing(B). Concave parts(G1) are formed on the outer surface of the spotters. The convex parts(G2) are formed in the tires. The tires are coupled to the outer surface of the spotters, and are contacted with the ground.
