A press machine having side frames which are effectively reinforced so as to appreciably reduce the noise generated during operation of the machine and improve the working accuracy of the machine without installing any special device on the outside thereof, significantly increasing the weight of the entire press machine, or obstructing a space between the side frames of the press machine. The side frames of the press machine are C-shaped in side view and are reinforced by at least one reinforcing member fixedly secured to each of the side frames at at least one predetermined place. The reinforcing members function to suppress the deformation of the opening of the C-shaped side frames to reduce noise and improve accuracy. The reinforcing members convert the vibrational energy of the side frames into heat energy which is then absorbed into the side frames.
