To facilitate reducing a distance between a pressurizing elastic element and a working position and, heighten a thrust nearby the processing position of a panel in a press device for processing an edge part of the panel while thrust fastening the panel with a pad.

This press device is provided with a pad holding means 10 between a bottom face of an upper holder 1 and an upper face of a pad 3 for guiding the pad 3 up/down freely against the upper holder 1, and restraining a descending position against the upper holder 1. A conventional pad guiding and holding mechanism is discontinued and a distance between a pressurization elastic element and a working position is made to be the minimum for giving sufficient thrust to nearby a panel working position.
