Abstract
A preload adjusting plug is inserted through a communication hole extending through center portions of a Zgear, a Zgear, and an inner ring of a nutation gear. A male thread portion is formed at an outer periphery of one end of the preload adjusting plug, and is screwed to a female thread portion formed at an inner periphery of the Zgear. A disc-shaped flange portion extending radially outward is formed at the other end of the preload adjusting plug, and axially presses a back face of the Zgear through a bearing. The preload adjusting plug applies predetermined preloads to meshing portions in the nutation gear mechanism.
