PROBLEM TO BE SOLVED: To provide a gear device capable of suppressing the leakage of grease to the outside of the device and an increase in the axial size.SOLUTION: A gear device 1 includes a housing 80, an internal gear 70 integrally formed in the housing 80, an external gear 30 arranged on the inner periphery side of the internal gear 70, a rotating shaft 20 for revolving the external gear 30, a side plate 50 for covering the external gear 30, an inside bearing 90 for supporting the rotating shaft 20 on the side plate 50, and an outside bearing 100 for supporting the side plate 50 on the housing 80. The inside bearing 90 has a first seal component 95 for sealing an internal space S1, a first inner ring 91 pressed into the rotating shaft 20, and a first outer ring 92 pressed into the side plate 50. The outside bearing 100 has a second seal component 105 for sealing an internal space S2, a second inner ring 101 pressed into the side plate 50, and a second outer ring 102 pressed into the housing 80. |
