Abstract: A reduction gear of the present invention is compact and light and can be used for tire portions of an apparatus for travelling, etc. Each of outer and inner pins is formed by a rolling bearing. The reduction gear includes block-shaped lubricating members which supply a lubricant to the outer rings of the outer pins to thereby lubricate them, and a ring-shaped lubricating member which supplies the lubricant to the outer rings of the inner pins to thereby lubricate them. The lubricant can be supplied to a pair of cycloid gears through the outer pins and the inner pins for lubrication. Since the cycloid gears, the outer pins, and the inner pins are lubricated by the lubricating members, the reduction gear can enhance its durability, reduce the friction between components to thereby lower the frictional resistance, and realize a light and compact structure.

Abstract: In an in-wheel motor driving device, since an involute speed reduction gear with a small difference in number of teeth which can be made small in size can be disposed on an inner side of an inner rotor type motor, a size of the in-wheel motor driving device in the direction of a rotational axis can be reduced. Further, in the inner rotor type motor, since a first stator is disposed so as to face a radially outer side of a large-diameter rotor, heat generated in the first stator is easily dissipated. On the other hand, in an outer rotor type motor, since a second stator is disposed so as to face a radially inner side of a small-diameter rotor, a torque radius of the small-diameter rotor can be made large, thereby making it possible to ensure a large torque capacity. Because of this, the outer rotor type motor can be made smaller in diameter than the inner rotor type motor, thereby making it possible to ensure a large space within a wheel.
