PROBLEM TO BE SOLVED: To provide a press machine where the loss of energy (press load) can be suppressed. SOLUTION: At the inside of a frame part 11 in a bolster carrier 9 to be mounted with a bolster 7, a rib 12 is formed so as to be crosswise, and the crossed part C1 of the rib 12 is supported by a strut 14 erected at the center of a die cushion housing part 13 in a bed 10. In this way, the center of the bolster 7 is supported by the strut 14 via the crossed part C1 of the rib 12 in the bolster carrier 9, and the bending of the center in the bolster 7 into a recessed shape by a press load can be prevented. Thus, the press load (energy) consumed for the deformation (bending) of the bolster 7 is reduced, so as to suppress the loss of the press load. COPYRIGHT: (C)2008,JPO&INPIT
