星歯車減速装置。[Scope of Claim for Utility Model Registration] (1) In a multi-stage planetary gear reduction device that decelerates and transmits the rotational force of a hydraulic motor to a rotated object, the rotational torque of the carrier of the first-stage planetary gear reduction mechanism is transferred to the sun gear of the next-stage planetary gear reduction mechanism. In the connection structure for transmission, the rotational torque of the preceding stage carrier is transmitted to the next stage by a spacer which is meshed with the preceding stage carrier at the large diameter part of the outer periphery and with the next stage sun gear at the small diameter part of the inner periphery, respectively, by gear couplings. A planetary gear reduction device characterized in that transmission is transmitted to a stepped sun gear. (2) The multi-stage planetary gear reduction device is a two-stage planetary gear reduction device, and the rotational torque of the carrier of the first stage planetary gear reduction mechanism is transmitted through a space provided with a large-diameter gear coupling portion and a small-diameter gear coupling portion. 2. The planetary gear reduction device according to claim 1, wherein the transmission is transmitted to a sun gear of the second stage planetary gear reduction mechanism.
