Abstract
A cam mechanism includes a base, a roller gear, and a camshaft. The roller gear and the camshaft are rotatably supported by the base. The roller gear has a turret and a plurality of cam followers mounted on the circumference of the turret. The camshaft has a shaft portion and a tapered rib having a first tapered rib and a second tapered rib. The first and second tapered ribs are each engaged with the cam followers. The first and second tapered ribs are configured to rotate relative to each other around a rotation axis of the shaft portion during adjustment of preload at which the first and second tapered ribs are pressed against the cam followers. After the adjustment of the preload, the second tapered rib is fixed to the shaft portion, and the first and second tapered ribs are prevented from rotating relatively.
