A rigid circular internal gear, a flexible external gear installed inside the internal gear and partially meshing with the gear, and a flexible external gear installed inside the external gear. In a wave generator or a radial harmonic gear device which bends the external gear into an elliptical shape so that it meshes with the internal gear on its long axis and rotates the ellipse, A groove is formed on the circumferential surface of the toothed gear at approximately the center of the tooth side, and lubricating oil is stored in the groove.On both sides of the lubricating oil storage groove, an internal gear and an external gear are formed. A harmonic gear device characterized in that an elastic seal ring is provided between each of the gears. 2. The elastic seal ring has the same number of teeth as the external gear on the side that contacts the external gear and is fixed to the gear, and the internal gear has a circumferential groove formed at a position corresponding to the ring. 2. The device according to claim 1, wherein the device is adapted to be able to move in and out of the groove. 3. Request for registration of a utility model characterized in that the elastic seal ring is bent in an ellipse along the external gear which is bent in an ellipse, and is adapted to fit into the circumferential groove of the internal gear on its long axis. The device according to item 2 of the scope of the invention.
