PROBLEM TO BE SOLVED: To provide a motion conversion mechanism which can place a large axial load on a clearance between a first disc and a second disc, and can easily position the first disc and the second disc in parallel with each other.SOLUTION: A roller cam mechanism has a first disc 2 and a second disc 3, and a plurality of rollers 4 which are arranged between an axial rear face 2b of the first disc 2 and an axial front face 3a of the second disc 3. A first cam face 6 is arranged at the axial rear face 2b of the first disc 2, a second cam face 7 is arranged at the axial front face 3a of the second disc 3, and the rollers 4 rollingly contact with the first cam face 6 and the second cam face 7 so that the relative movement of the rollers in an axial direction is converted into the relative rotation of the first disc 2 and the second disc 3 when the first disc 2 and the second disc 3 relatively move in the axial direction.SELECTED DRAWING: Figure 1 |
