Abstract
Angle (.theta.) formed by straight lines (A, B) connecting a fixed shaft (23) and two connecting shafts (24, 25) of a triaxial link (16) of a slide drive unit (10) is set acute, so that position of a slide at any crank angle can be made higher than a conventional arrangement throughout the entire slide motion and the slide can be located above a height necessary for conveying a workpiece for a longer time per the same cycle speed, thereby driving a transfer feeder with sufficient time, allowing secure conveyance of the workpiece while improving productivity of a press and avoiding restriction of design.
