    • In order to improve rigidity and stability, shorten a whole length, reduce the number of component parts and assembling steps in an inscribed meshing planetary gear construction, a flange part 114 of an output shaft 102, inner pins 107 and support ring 117 are supported at both ends by bearings 115a and 115b, and then a reduction mechanism part is assembled between bearings 115a and 115b. Axial position of the inner pins 107 are set by inner rings 124a and 124b of the bearings 115a and 115b. Subsequently, with respect to inner pins 107, it is not necessary to provide any shoulder or treading, and the shape is allowed to be simplified, so that machining for high hardness and high accuracy can be realized at low cost, and then a predetermined quality can be secured together with both supporting structures without requiring any expensive inner rollers. This constitution can also be applied in the epicyclic gear construction having a carrier pin 116.

    • A geared motor 101 comprising a reduction gear unit 102 of oscillating internal meshing planetary gear structure type and a motor unit 103 coupled to each other, the reduction gear unit 102 having a first shaft 111 and a second shaft 112 located on its center axis L, external gears 115a and 115b being fitted on the outer periphery of the first shaft so as to be capable of oscillating rotations, an internal gear 120 with which the external gears mesh internally being provided concentrically with the first shaft, the second shaft being coupled to the external gears via means 117 for extracting the rotational components of the external gears. A simple planetary roller mechanism 202 for transmitting rotational power by means of the friction between rollers is interposed between the reduction gear unit and the motor unit to reduce the vibration and noise levels greatly.
