The present invention provides an omni-directional wheel structure, comprising: a wheel which are arranged side by side to each other and provided with at least three of which, each of which is rotationally installed on a main shaft; and a plurality of rotatable rollers installed along the circumferential direction at an edge of each wheel. A plurality of rollers disposed on wheels adjacent to each other are disposed to overlap each other by a predetermined distance so as to be in contact with a ground at the same time. An objective of the present invention is to provide the omni-directional wheel structure in which vibration and noise are low, and a load is evenly distributed.
