To provide an opening outward in an emergency by providing a door panel on a toilet booth in a center hoisted condition with inward-opening style, embedding a hard material in one end of a hanging side, and projectingly providing an elastic material on one end of the opening side to provide a cover.

An edge material 7 is adhered to a peripheral edge of a hollow core 6 such as a honeycomb core, and then, the face and back sides are covered with a plate base material 8 and a decorative material 9 to form a door panel 1. The panel 1 is center-hanged in a toilet booth through a gravity hinge or the like provided on a hanging side in an inward-opening style. A hard material 11a is embedded in one end on the hanging side of the panel 1, and an elastic material 12a having a hollow part for a cover on one end on the opening side is projectingly provided so as to reach the hard material 11b embedded in a receiving side panel 3. An elastic material 12b is projectingly provided to make a cover in one end on the panel 1 side of the hanging side panel 2 so as to reach the hard material 11a. In an emergency, when the panel 1 is pulled by a hand through upper and lower spaces, the elastic material 12 is deformed without breakage, and the panel 1 can be opened outwardly.
