PURPOSE: A device for adjusting a vertical shaft of an attachment is provided to precisely adjust the position of a vacuum absorption cup by adjusting a gap between a panel and the vacuum absorption cup. CONSTITUTION: A device for adjusting a vertical shaft of an attachment is composed of a fixed frame(45) mounted to a sub frame, a multi-step cylinder(47) installed at one side of the fixed frame and having a vacuum absorption cup(23), a flexible screw shaft(49) installed in the multi-step cylinder and connected to the vacuum absorption cup, and an actuator(55). The actuator is connected to the flexible screw shaft by a driving gear(51) and a driven gear(53), and moves the flexible screw shaft up and down so that the multi-step cylinder is expanded and contracted.
