Abstract
A strain wave gear device includes: an internal gear; a wave generator; a flex gear including an outer gear and a first annular portion integrally formed with the outer gear of the same material; and an outputter that rotates together with the flex gear and includes a second annular portion facing against the first annular portion in a radial direction centered on an axis. The second annular portion is provided with a transmission tooth protruding radially while the first annular portion is provided with a recess to receive the transmission tooth. The recess is circumferentially wider than the transmission tooth and tolerates relative circumferential displacement of the flex gear with respect to the outputter. Transmission pairs, each including the transmission tooth and the recess, are circumferentially arranged.
