ABSTRACT:
The reduction gear includes a plurality of first and second rollers that are disposed so as to directly come into rolling contact with the outer peripheries of first and second eccentric bodies; first and second retainers that maintain gaps between the first and second rollers in the circumferential direction of the first and second eccentric bodies; and first and second guide bodies of which the movement in the axial direction is restricted and which restrict the movement of the first and second rollers in the axial direction by coming into direct contact with ends of the first and second rollers.
