    Abstract: Provided are a drive mechanism capable of improving stability of steering environment and operation rate of power sources, and an omnidirectional moving vehicle using this drive mechanism. The omnidirectional moving vehicle comprises a vehicle body (6), and a plurality of wheels (4a to 4d) at least two wheels of which are equipped with the steering drive mechanism. The drive mechanism comprises a rotatable steering unit (1), a wheel (4) supported by the steering unit, a drive member (2) rotating about an axis extending along a center axis of the steering unit, an output shaft (3) located at an offset position from the center axis of the steering unit and transmitting rotational force of the drive member to the wheel. The drive member comprises a first drive unit (22) driven in a forward rotation direction and a second drive unit (23) driven in a reverse rotation direction and located coaxially with the first drive unit. The output shaft is provided with a first output unit (71) to which driving force is transmitted from the first drive unit, and a second output unit (72) to which driving force is transmitted from a conversion unit for converting rotation of the second drive unit, is restricted by both the output units, and transmits rotational force obtained from the output units to the wheel.

    Abstract: A reduction gear transmission is realized in which the total speed reduction ratio is adjusted to a desired value without making any changes to a rotation direction changing gear mechanism or a speed reduction unit.
    The rotation direction changing gear mechanism comprises an input shaft and an input gear that rotates together with the input shaft, and an intermediate gear that is orthogonal to the input shaft and meshes therewith. A reduction ratio adjusting gear mechanism comprises a first spur gear that rotates together with the intermediate gear, a second spur gear that meshes with the first spur gear, and a third spur gear that meshes with the second spur gear. The speed reduction unit comprises a crankshaft that rotates together with the third spur gear and causes an eccentric cam to rotate eccentrically, an external gear that revolves orbitally while being engaged with the eccentric cam, and an internal gear that surrounds the external gear while meshing with the external gear, and that has a number of teeth differing from the number of teeth of the external gear. The reduction gear transmission is capable of changing its total speed reduction ratio by changing at least one gear out of the first spur gear, the second spur gear, or the third spur gear into another gear having a differing number of teeth.
