PURPOSE: To provide a titled dynamic balancer which is so constituted as to obtain roughly perfectly dynamic balance by providing weights which face each other via pinions and move upward and downward while meshing each other to a slide of a press machine.

CONSTITUTION: A slide 3 is connected to the plural eccentric parts 1a of a crank shaft 1 supported by a press machine. Balance weights 4 are fixed to the shaft 1 in accordance with the parts 1a. Racks 5 are provided on both side faces of the slide 3 and are meshed with the pinions 7 provided to the shaft fixed to the machine body. Weights 9 having the racks 8 facing the racks 5 and meshing with the pinions 7 are provided freely upward and downward movably to the machine body. The slide 3 is connected via a rod 10 to the piston 12 of a cylinder 11 and both weights are connected via rods 13 to the pistons 15 of cylinders 14. The cylinders 11, 14 are connected by a pipe 16, and the required pressure of the compressed air to be supplied is maintained constant and the same.
