<p><P>PROBLEM TO BE SOLVED: To provide a cam actuator having a cam whose driving shaft is fixed firmly. <P>SOLUTION: The cam actuator comprises some cams 20 forming at least one traveling orbital 20A, 20B for a following roller. Each cam has an aligning reaming on a driving shaft 22, and a means for adding fastening force parallel to the driving shaft is installed and has a noncircular cross section 22C, 22D. At least one facing ring spacer 26 has noncircular inner edge 26C, 26D so as to allow the shaft-direction dislocation along the shaft 22, and is designed so as to fix the facing ring spacer and the shaft under the rotation, and arranged at the periphery of the bearing by contacting with at least one cam. The facing ring spacer 26 is fixed to the cam 20 by adhesive power, and fixed to the shaft 22 by the cooperation of shapes caused by supplementary protrusions 22C, 22D, 26C, 26D formed on the shaft 22 and the facing ring spacer 26. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
