An internal-tooth gear (2) is provided with an annular gear body (22), and a plurality of pins (23) that are held on the inner peripheral surface of the gear body (22) in a self-rotating state and constitute internal teeth (21). A planetary gear (3) is provided with external teeth (31) partially meshed with the internal teeth (21). A plurality of inner pins (4), when in a state of being inserted into a plurality of inner pin holes (32) formed in the planetary gear (3), revolve in the inner pin holes (32) and rotate relative to the gear body (22). A first bearing component (6A) can rotatably support the plurality of inner pins (4) on the gear body (22). The first bearing component (6A) is provided with a first inner ring (61), a first outer ring (62), and a plurality of bearing pins (63). The plurality of bearing pins (63) are held between the first inner ring (61) and the first outer ring (62) in a self-rotating state. For the plurality of pins (23) and the plurality of bearing pins (63), the respective diameters are different, and the holding structures are different.
