Abstract
A speed reducing mechanism according to one embodiment includes an output shaft, carriers each of which has an output shaft hole, and oscillating gears each of which has an output shaft insertion hole. The output shaft is inserted in the output shaft hole and the output shaft insertion hole and contacts the inner peripheral surfaces. The surface roughness Ra of the inner peripheral surfaces defining the output shaft hole and output shaft insertion hole is equal to or less than 1.6 μm. The static friction coefficient of the inner peripheral surfaces against the output shaft is equal to or less than 0.2.
