Abstract:
1. An output gear-equipped reduction device comprising: a casing; a reduction mechanism housed within the casing; an output flange for taking out rotation reduced by the reduction mechanism; an output shaft provided on the output flange and having a smaller diameter than the output flange; and an output gear provided on the output shaft and having an addendum circle greater than the diameter of the output shaft, wherein the output flange, the output shaft, and the output gear are integrally formed as an output flange section, an output shaft section, and an output gear section of a single output member in that order in the axial direction with the above-stated dimensional relationship maintained, wherein the integral output member is supported at the output shaft section by the casing via bearing means, wherein the casing has a plurality of recesses which house the rolling elements of the bearing means, and a retainer of the rolling elements in the circumferential direction of the output shaft section is formed between the recesses, and wherein the recesses are set to the position and size such that the teeth of the output gear section can pass through the recesses in the axial direction.
