PROBLEM TO BE SOLVED: To shorten the axial length of a reduction gear. SOLUTION: The reduction gear includes: a plurality of first and second rollers 55A, 55B capable of making direct roll contact with the outer peripheries of first and second eccentric bodies 54A, 54B; first and second retainers 94A, 94B for maintaining a clearance in the circumferential direction of the first and second eccentric bodies 54A, 54B of the first and second rollers 55A, 55B; and first and second guide bodies 96A, 96B that are restricted in axial movement, for restricting axial movement of the first and second rollers 55A, 55B by directly coming in contact with axial ends of the first and second rollers 55A, 55B.
