<p>PROBLEM TO BE SOLVED: To provide a speed reducer with relative differential rotation between an internal gear and an external gear meshing with the internal gear, which can drive a plurality of output shafts in different speed reduction ratios.SOLUTION: A speed reducer includes an input shaft 12, a first output shaft 16, a second output shaft 18, a stationary part 10, first speed reducing means 20 provided between the input shaft 12 and the first output shaft 16, and second speed reducing means 22 provided between the first speed reducing means 20 and the second output shaft 18. A speed reduction ratio of the first speed reducing means 20 and a speed reduction ratio of the second speed reducing means 22 are set to different values.</p> |
