ヨン装置。[Claims for Utility Model Registration] A bolster in which a plurality of pin holes are formed and a press die is placed thereon, a cushion pin slidably inserted into the pin hole, and a piston rod placed on a dictation that is connected to the cushion pin. a hydraulic cylinder abutting a lower end; an oil discharge passage formed at the bottom of the cylinder; and a hydraulic cylinder slidably inserted into the bottom of the cylinder and capable of coming into contact with the piston rod and opening and closing the oil discharge passage. a spool; and a resilient means for resiliently biasing the spool upward to protrude from the bottom of the cylinder, and before the press mold is placed on the bolster, the piston rod moves through the oil discharge path. The cushion pin protrudes from the bolster by being pushed up by the closing spool, and when the press die is placed on the bolster, the cushion pin in contact with the press die is pushed down, causing the spool to move downward. A cushion device for a press machine, characterized in that the oil discharge passage is opened by opening the oil discharge passage.
