A rigid circular internal gear, a flexible external gear provided inside the internal gear and partially meshing with the gear, and a flexible external gear provided inside the external gear. a wave generator that bends the external gear into an elliptical shape so that it meshes with the internal gear on its long axis and rotates the ellipse, and the wave generator has a flexible A bearing in which a large number of balls are arranged between an outer ring and an inner ring, and the outer ring fits inside the external gear, and a bearing that fits inside the inner ring of this bearing to flex the bearing and the external gear into an oval shape. and a cam plate connected to an input shaft that rotates the ellipse, wherein ring-shaped seal plates are provided on both sides of a retainer that holds the balls of the bearing at equal intervals, The radially outer peripheral edge of the seal plate is accommodated in an annular recess formed in the outer ring, and the radially inner circumferential edge of the seal plate is accommodated in an annular recess formed in the inner ring. A harmonic gear device characterized in that a space between an inner ring and an outer ring is filled with a lubricant. 2. A request for registration of a utility model characterized in that a ring made of a flexible material and having an L-shaped cross section is fixed to each concave portion of each ring and the outer ring, and the side edge of the seal plate is in contact with the ring. The device according to item 1. 3. The device according to claim 1, wherein one of the seal plates is formed integrally with the retainer, and the other seal plate is attached to the retainer via a split pin.
