PURPOSE: An omnidirectional spherical wheel with plural rollers is provided to minimize friction resistance, to change the direction easily, and to move actively in all directions against load or rolling friction by mounting a roller or more to the wheel. CONSTITUTION: A roller set(30) is formed in an upper case(21), and a roller(31) is rotated and mounted to a shaft rotating groove(36) of a roller support bar(35). The roller is integrally formed with a roller shaft(32), and plural rollers are installed to the roller support bar around a spherical wheel(11). The contact point or line of the roller and the spherical wheel is placed higher than the horizontal central line of the spherical wheel to support load applied to the spherical wheel and to rotate the rollers. The spherical wheel is inserted to the upper case, and a lower case(22) is combined with the upper case by a connector(23). The gap is formed between the end of the lower case and the spherical wheel, and a wheel set(10) is installed to a movable body by attaching a plate(41) to the case.
