Abstract
A gear unit has a washer which is provided at a position where the washer is able to come into contact with a retainer of roller bearings provided to each of adjacent eccentric parts in a crank shaft, and which regulates a movement of the roller bearing in an axial direction. A housing recess which houses the washer is formed on at least one face of the faces of adjacent oscillating gears facing each other. The housing recess includes an axial direction regulating surface which regulates movement of the washer in the axial direction, and a radial direction regulating surface which regulates movement of the washer in the radial direction.
