PROBLEM TO BE SOLVED: To provide a press machine capable of improving a working precision better than a conventional way further having a compact constitution in the press machine in which a slide is supported by plungers of two points or more. SOLUTION: Link bodies consisting of a first link 12, a second link 14, and a pivot shaft pivotaly supporting the first link 12/second link 14 are plurally arranged in the same direction, the first links 12 of four pieces is turnably supported to a machine frame 1 by two fixing support shafts 11 on the same axial line, the second links 14 of three pieces are pivotaly supported with moving support shafts 13 arranged to plungers 3 of three pieces connected to a slide 5 on the same axial line, further, the first link and the second link 14 are connected by one pivot shaft 15. Drive links 18 of two pieces supported to a crank shaft are pivotaly supported to the pivot shaft 15.
