ABSTRACT:
A reducer having an inner gearing planetary gear speed reduction mechanism is provided, which costs low and can be easily installed. A driving device is provided with a planetary gear speed reduction mechanism having an internal gear and an external gear which internally meshes with the internal gear. The planetary gear speed reduction mechanism makes one of the internal gear and the external gear (the external gear in the drawing) rotate on its axis with an oscillating movement in accordance with a rotation of an input shaft.
