Abstract
A rotary ring () formed such that an outer circumference is eccentric with respect to an inner circumference is provided to an outer circumference of an eccentric drum () of an eccentric shaft (). An adjustment ring () formed such that an outer circumference is eccentric with respect to an inner circumference is provided to the outer circumference of the rotary ring (), and a slide () is mounted to the outer circumference of the adjustment ring (). Since the slide () and a slide drive unit () are arranged to be superposed substantially at the same height, a distance between the slide drive unit () and a lower end of the slide () can be reduced and the entire height of a servo press () can be reduced. In addition, since the height position of the slide () can be finely adjusted by rotating the adjustment ring (), a press working can be performed with high accuracy.
