Abstract
A conveyance device includes a fixed base, a turning body, two or more servomotors, a conveyance arm, and two or more speed reducers. The turning body includes a large gear serving as an external gear. Each of the speed reducers includes a housing integrated with the fixed base, a planetary carrier rotatably supported inside the housing, an internal gear provided inside the housing, a sun gear connected to an output shaft of one of the servomotors, a plurality of planetary gears arranged around the sun gear and rotatably supported by the planetary carrier, and an output gear that rotates integrally with the planetary carrier. The planetary gear meshes with the sun gear and meshes with the internal gear. The output gear has a smaller diameter than a diameter of the large gear and meshes with the large gear outside the large gear.
