摘要： PROBLEM TO BE SOLVED: To provide a cam mechanism device that can suppress the vibration at integer times the number of revolutions of a cam. SOLUTION: In a cam mechanism device 5 having both a cam 2 and a cam follower 4 for transmitting the displacement of the cam 2, the cam 3 is formed based on a cam curve, which can be obtained by removing a frequency component having the frequency equal to integer times the number of revolutions of a cam 2 from a cam curve which determines the movement of the cam mechanism device 5. Accordingly, the vibration whose frequency equals interger times the number of revolutions of the cam 2 can be suppressed, thereby lowering the vibration of the cam mechanism device 5.
