ABSTRACT:
A planetary gear apparatus has an external gear mounted on an input shaft through an eccentric member, and an internal gear which engages with the external gear and is concentric with respect to an output shaft. A recess is provided in the output shaft, and internal or external splines are provided on either the inner or outer side of the recess so as to be concentric with respect to the output shaft. The external gear has either a carrier or an annular groove provided on the side thereof which is closer to the output shaft. The carrier or the annular groove is provided with internal or external splines so as to be concentric with respect to the external gear. The internal or external splines on the output shaft and the internal or external splines on the external gear are operatively connected together by a drive having external or internal splines provided at both ends thereof. The drive is constituted by a hollow shaft having a through-hole. The input shaft is received through the through-hole in the drive and is rotatably born within the recess of the output shaft.
