The gear unit(1) is provided with washers (21), which are provided at a position that can contact the cages (18b) of the roller bearings (18) provided in each of the adjacent eccentric sections (8a) of a crankshaft (8) and which regulate the movement of the roller bearings (18) in the axial direction. On at least one of the surfaces of the adjacent nutating gears (10) that face each other, a seating recess (22) in which the washer (21) is seated is formed. The seating recess (22) has an axial direction-regulating surface (22a) for regulating the movement of the washer (21) in the axial direction and a radial direction-regulating surface (22b) for regulating the movement of the washer (21) in the radial direction. |
