Abstract
A drive device including a planetary gear reduction device having at least two stages and an output shaft, and a driven shaft to support a driven member rotatively driven by torque reduced by the planetary gear reduction device and transmit the torque from the output shaft to the driven member. Each stage of the planetary gear reduction device includes a sun gear, an outer gear, multiple planetary gears, a carrier, and a support shaft. The output shaft is provided to the carrier of the last stage. Central axes of the sun gear, the outer gear, the carrier, the output shaft, the driven shaft, and the driven member are all arranged coaxially with one another and at least one carrier is floatingly supported relative to the outer gear. The carrier is formed as a single integrated unit having holes into which both ends of the support shaft are fitted.
