Claims

[Scope of Claim for Utility Model Registration] Of both long edges on the back side of the ceiling board, a field edge member that is suspended and supported from the ceiling frame side by a hanging metal fitting is fixed to one side along the same edge. A crosspiece member is fixed to the long edge on the other side along the edge, and a joint forming piece extends approximately horizontally and outward from the side edge of either the field edge member or the crosspiece member along the longitudinal direction. The ceiling board is a ceiling board that protrudes toward the direction, and the end portion of the joint forming piece is hooked onto a part of the edge member, the crosspiece member, or the hanging metal fitting, so that the ceiling board A ceiling board characterized in that a hook part is formed to prevent the ceiling board from falling off.
