ABSTRACT OF THE DISCLOSURE The crank driving device for press according to the present invention is designed in serial type eccentric structure, in which the eccentric element of crank shaft and the eccentric mechanism to give the second eccentricity are separated in axial direc- tion of the crank shaft. Specifically, in each of the eccentric holes of a pair of rotating bodies supported synchronously and rotatably on basic axial line, each of the shaft ends of crank shaft is rela- tively rotatably and relatively displaceably engaged in axial direction. The eccentricity is adjusted by relatively rotating crank shaft and rotating bodies, and the relative angle of crank shaft and rotating bodies are maintained at constant value by connecting means after adjustment. Therefore, the slide strokes can be easily adjusted as desired while pressure speed is maintained at constant level by adjusting the eccentricity of crank unit and eccentric holes, and this contributes to compact design of the equipment.
