PROBLEM TO BE SOLVED: To eliminate an abrupt change in the vicinity of each control point to control an output shaft substantially faithfully to a synchronous curve, when setting the synchronous curve by a line plot obtained by connecting a plurality of control points in order. SOLUTION: The plurality of control points are set by XY coordinates on an XY plane when an X-axis is used for displacement amounts of an input shaft, and when a Y-axis is used for displacement amounts of the output shaft, an X-axis-directional acceleration section AP around an X-coordinate of the each control point as the center is set in each of the plurality of control points, the graph of broken line is generated tentatively by connecting temporarily the plurality of control points in order with straight lines along an X-axis direction, one-portions of the straight lines L1, L2 constituting the line plot are deleted as to the acceleration section AP in the each of the plurality of control points, and a smooth line plot provided by connecting end points of the straight lines L1, L2 in both sides with a curved line CL contacting respectively with the straight lines L1, L2 serves as the synchronous curve.
