A rotary ring (34) formed such that an outer circumference is eccentric
with respect to an inner circumference is provided to an outer
circumference of an eccentric drum (333) of an eccentric shaft (33). An
adjustment ring (41) formed such that an outer circumference is eccentric
with respect to an inner circumference is provided to the outer
circumference of the rotary ring (34), and a slide (5) is mounted to the
outer circumference of the adjustment ring (41). Since the slide (5) and
a slide drive unit (30) are arranged to be superposed substantially at
the same height, a distance between the slide drive unit (30) and a lower
end of the slide (5) can be reduced and the entire height of a servo
press (1) can be reduced. In addition, since the height position of the
slide (5) can be finely adjusted by rotating the adjustment ring (41), a
press working can be performed with high accuracy.
