A press machine includes: a ram, a shaft, and three or more ram driving cams, for the one ram, configured to push down the ram toward a bottom dead center, the plurality of ram driving cams being integrally rotatable with the common shaft. Both end portions of the shaft are rotatably supported by a pair of rotation support portions fitted to the both end portions between which all of the plurality of ram driving cams are disposed, and an intermediate portion of the shaft disposed between the ram driving cams is rotatably supported by a support groove opened downward. The plurality of ram driving cams includes at least two lifting and lowering cams configured to apply both a pushing down force and a pushing up force to the ram, and at least one lowering cam configured to apply only the pushing down force to the ram.
