A dynamic balance device of a press machine is provided with a plurality of cam parts 80 for transmitting up and down motion of a slide to balance weights 70 and actuating the balance weights 70 in the opposite direction of the up and down motion of the slide. The cam parts 80 are provided so as to be capable of moving in a direction substantially orthogonal to the actuated direction of the slide, and each cam part 80 is provided with a first inclined surface 81 having an angle of inclination corresponding to the angle of inclination of an inclined surface 31 formed in a member 30 that is provided integrally with the slide and that moves up and down with the slide, and a second inclined surface 82 having an angle of inclination corresponding to the angle of inclination of an inclined surface 71 formed in each of the balance weights 70. |
