ABSTRACT:
A harmonic gear apparatus includes a tubular circular spline having a multiplicity of teeth on an inner periphery thereof, and a flexible spline disposed in the circular spline and having a multiplicity of teeth on an outer periphery thereof, the number of which is smaller than that of the circular spline. A flexion generating member rotatably mounted on a rotary shaft is rotatably disposed in the flexible spline. A generally annular flexible supporting member supports one end of the flexible spline in such a manner that the flexible spline is able to flex in a radial direction but has a significant rigidity in the circumferential direction. When the spline is flexed while the flexion generation member rotates in the flexible spline, some of its teeth engage with some of the teeth of the circular spline thereby rotating the circular spline.
