The present invention relates to an omnidirectional drive apparatus capable of being omnidirectionally driven by a steering motor and a plurality of drive units arranged to surround the steering motor. According to one embodiment of the present invention, the omnidirectional drive apparatus driven comprises: the steering motor to be omnidirectionally steered; the drive units including a wheel, a drive motor providing driving power to the wheel, and a drive frame supporting the wheel to be able to rotate; and a housing mounting the steering motor and the drive units thereon. The drive units form a radial shape with respect to the steering motor. Moreover, at least one pair of drive units among the drive units are placed in a direction opposite to the center of the steering motor and are connected to the steering motor by a power transfer means for the advancing directions of at least one pair of drive units to be simultaneously adjusted when the steering motor is rotated.
