PROBLEM TO BE SOLVED: To provide a press device capable of accurately adjusting a stroke amount of a slide. SOLUTION: The device is equipped with a pair of crankshafts 6a, 6b having rotary shafts 48a, 48b and crank parts 50a, 50b, a pair of connecting rods 10a, 10b rotatably coupled to each crank part 50a, 50b in the crankshafts 6a, 6b respectively through the medium of eccentric bushes 8a, 8b and a slide reciprocatingly moved toward a processing area. A stroke amount adjusting mechanism 76 adjusts the relative angle positions of the eccentric bushes 8a, 8b with respect to each crank part 50a, 50b in a pair of crankshafts 6a, 6b by relatively rotating the eccentric bushes 8a, 8b of the connecting rods 10a, 10b with respect to each of the crankshafts 6a, 6b.
