PROBLEM TO BE SOLVED: To provide a press where the production and an assembling operation of the eccentric mechanism in consideration of phase matching can be facilitated, when an eccentric mechanism provided with an eccentric drum is used. SOLUTION: The eccentric mechanism 24 for slide elevation in a servo press is composed of: a connecting rod 243; and an eccentric drum 242 freely rotatable to the connecting rod 243. The eccentric drum 242 is composed of: a big eccentric part 244 stored into the connecting rod 243; a small eccentric part 245 having an eccentric shaft 241 eccentric to the center of rotation in the big eccentric part 244, and to be inserted into the big eccentric part 244; and knock pins 247 of fixing the big eccentric part 244 and the small eccentric part 245 each other; wherein the conventional spline engagement in the respective eccentric parts 244, 245 is abolished.
