する遊星歯車減速装置。 a support member, a housing rotatably supported by the support member via a bearing, a rotation source provided on the support member to rotationally drive the housing, and a rotation source that decelerates the output rotation of the rotation source to rotate the housing. In order to transmit data to the housing, a multi-stage reduction gear mechanism is provided, which includes a sun gear, a planetary gear that meshes with the sun gear, and a carrier that supports the planetary gear. A planetary gear reduction device in which the bearing is positioned in the rotational direction by a support member, the bearing is positioned in the axial direction by a nut screwed onto the support member, and the nut is stopped from rotating by a key plate and a bolt. In the device,
The side plate of the final stage carrier is provided with a notch located radially inward from the bolt, and by bringing the side plate close to the key plate side, the overall axial dimension can be shortened. Characteristic planetary gear reduction device.
