る遊星歯車減速装置。 A housing fixed to a machine frame, a drum rotatably supported by the housing and having an internal gear formed on its inner peripheral surface, a motor provided on the housing for rotationally driving the drum, and the motor. A multi-stage planetary gear reduction stage comprising a sun gear, a planetary gear meshing with the sun gear and the internal gear, and a carrier rotatably supporting the planetary gear. Of the carriers constituting each planetary gear reduction stage, the first stage carrier is a movable carrier connected to the next stage sun gear, and the last stage carrier is a cantilever pin-shaped carrier provided in the housing. In a planetary gear reduction gear that is a fixed carrier, an annular projection is provided on the output side surface of the preceding stage carrier over the entire circumference, and the annular projection is brought into contact with the input side surface of the next stage planetary gear. A planetary gear reduction device characterized in that it is configured to prevent the next-stage planetary gear from moving in the axial direction.
