<p>A gear device 1 includes an outer cylinder 2, a plurality of crank shafts 20, a carrier 4 which rotatably supports the plurality of crank shafts 20 and rotates relative to the outer cylinder 2 in synchronization with the rotation of the crank shafts 20, a plurality of spur gears 18 which are fixed coaxially with the crank shafts 20 at portions extending toward an outer side of the carrier 4 in the crank shafts 20, an input gear 16 which includes a gear part 16a that engages with the plurality of spur gears 18, and transmits rotational drive force to each of the spur gears 18, and washer means comprising washers 41, 42 disposed outside the carrier 4. The input gear 16 is regulated from moving in a radial direction of the input gear 16 by engaging with the plurality of spur gears 18 at a position outside the carrier 4 in an axial direction, and regulated from moving in an axial direction of the input gear 16 by the washers 41, 42 of the washer means.</p> |
