Claims

[Claims for Utility Model Registration] First and second cams are arranged side by side on a cam shaft that is rotatably supported on a base, and the first and second cams are pivotally mounted on the cam surface of the cam shaft using the respective support shafts as fulcrums. The cam followers attached to the first and second cam levers are in constant pressure contact with each other, and the rotation of the camshaft causes the first and second cam levers to swing about their respective supporting shafts via the cams and cam followers, and the tips thereof are rotated. In a cam mechanism that advances and retreats in the X-X direction and the Y-Y direction, the cam followers attached to the first and second cam levers are fixed to the cam lever and the base, respectively, at both ends of the first and second plates. The first and second
A cam mechanism characterized by being in constant pressure contact with the cam surface of the cam.
