Abstract
The present invention provides a reduction mechanism in which high torque output can he achieved, thinness and size and weight reduction can be achieved, and the number of teeth of a gear and reduction ratio can be freely set. In a gear motor that includes a reduction mechanism in which a planetary two-stage gear is arrayed between a sun gear of a planetary gear mechanism and an internal gear of a planetary gear mechanism, the reduction mechanism has at least a single planetary two-stage gear arrayed such as to be positioned between the sun gear and the internal gear and including a small gear or a large gear that meshes together with a large gear or a small gear of the planetary two-stage gear, and both end portions of the at least a single planetary two-stage gear are supported by ball bearings.
