PROBLEM TO BE SOLVED: To provide a press machine which can smoothen the transmission of rotation drive force between a plurality of crankshafts, further improves processing precision by improving the start-up performance of the press machine, and comprises a structure improved to enable the acceleration of molding cycles.SOLUTION: A press machine 10 is configured by mounting first coupling levers 48, 48 for rotating a plurality of crankshafts 34, 34, 34 having main shafts 30, 30 and eccentric shafts 32 by synchronizing with one another, respectively, to the eccentric shafts 32, 32, 32, while by mounting second coupling levers 56, respectively, to pins 54, 54, 54 integrally provided at circumferential positions different from those of the eccentric shafts 32 to the main shafts 30 with respect to the crankshafts 34, 34, 34.SELECTED DRAWING: Figure 2 |
