PROBLEM TO BE SOLVED: To provide a slide adjusting device of a forging press which can rapidly and smoothly adjust the shut height while a slide is stopped at a top dead center, and maintain the thickness accuracy of a forging at a predetermined value. SOLUTION: The forging press 1 with a lower portion of a connecting rod 30 to an upper portion of the slide 40 via an eccentric wrist pin 45 comprises a partial pinion 61 mounted on a lower portion of the eccentric wrist pin 45 and concentric with the eccentric wrist pin 45, a rack bar 62r having a rack 62 engaged with the partial pinion 61, and a hydraulic cylinder 63 for adjustment which reciprocates the rack bar 62r in the axial direction thereof. Since the hydraulic cylinder 63 for adjustment is put into the reciprocating motion, and the motion thereof rotates the eccentric wrist pin 45 directly via the engagement of the rack 62 with the partial pinion 61, the eccentric wrist pin 45 is rotated at a high speed, and thus, the shut height can be adjusted at a high speed.
