Abstract

A reduction gear in which an output shaft rotatably supports two planet gears engaging an internal gear fixed to a housing and a pinion gear at the end of the input shaft. The supports on the output shaft for the planet gears are circumferentially movable with respect to each other in order to eliminate back-lash.
