A second shaft (23) is configured by a shaft portion (91) extending outside a housing (21) in which a nutation gear mechanism (25) is housed, a housing portion (92), and a cylindrical portion (93). A communicating hole (94), through which an outside and an inside of the housing portion (92) communicate with each other, is formed in the shaft portion (91). A preload applying mechanism (79) includes a preload adjusting plug (101) that is screwed to the housing portion (92) and is able to be operated from outside through the communicating hole (94), a wave washer (104) compressed in accordance with a position of the preload adjusting plug (101), and a lock nut (111) that is screwed to the housing portion (92) of the second shaft (23) so as to press the preload adjusting plug (101) toward the nutation gear mechanism (25).
