Abstract
A speed reducing apparatus is provided which can prevent nonuniformity from occurring in output torque. A speed reducing apparatus that causes a first face gear to incline in such a manner as to mesh with a second face gear and causes the first face gear to oscillate in such a manner as to move a meshing portion in a circumferential direction includes a ball spline portion that supports the first face gear in an inclinable manner. The ball spline portion includes an outer ring, an inner ring, a ball capable of rolling along a ball groove of the outer ring and a ball groove of the inner ring, and a cage having a pocket in which the ball is incorporated, and allows axial displacement of the first face gear.
