Abstract: Provided is cam curve generating device that generates a cam curve that is smoothly connected to an out-section cam curve and reduces fluctuations in speed of a driven shaft and acceleration of the driven shaft. Cam curve generating device includes section divider that divides an application section into a plurality of sub-sections, and cam curve generator that generates a cam curve in the application section. The division condition includes a length and the type of each of the plurality of sub-sections. The boundary condition includes a position, speed, and acceleration of the driven shaft at each of a start and an end of the application section. Cam curve generator generates a cam curve that allows a position of the driven shaft, speed of the driven shaft, and acceleration of the driven shaft to be continuous at each of boundaries of the plurality of sub-sections.
