In a flexible mesh gear device in which rotation causes relative rotation between a first internal gear and a second internal gear, the shape of each tooth of the external gear is similar to that of the first internal gear. A flexible mesh gear device characterized in that a tooth thickness is formed to be thinner at a boundary portion between a portion that contacts and a portion that contacts the second internal gear.
