An omnidirectional vehicle having at least three wheels which can be steered in a given directions to allow the vehicle to travel in any direction, comprises a large steering gear horizontally and rotatably mounted at a body, a motor for driving the large steering gear, steering shafts numbering the same as the wheels, extending vertically around the large steering gear and adapted to rotatably support the wheels at lower ends of the steering shafts, and small steering gears numbering the same as the steering shafts and concentricably fixed to the steering shafts, respectively, so as to mesh with the large steering gear and adapted to rotate the steering shafts upon rotation of the large steering gear to change the steering directions of the wheels. The steering shafts may be hollow shafts. The vehicle may further comprises a large drive gear horizontally and rotatably mounted on the body so as to be concentric with the large steering gear and connected to a drive motor, drive shafts inserted in holes of the hollow shafts so as to be rotatably supported by the hollow shafts, small drive gears meshed with the large drive gear and concentrically fixed to the drive shafts to transmit rotational force from the large drive gear to the drive shafts, and rotational force transmitting gears for transmitting the rotational force from the drive shafts to the wheels while allowing steering of the wheels.
