ABSTRACT:
A self-contained tent includes a flat rectangular case which can be freely opened or closed. A tent sheet and a plurality of substantially U-shaped frame pipes are held in the case. The two ends of each frame pipe are pivotally supported in the case through a pair of supports. When the tent sheet is held in the case, the sheet covers the frame pipes. An edge of the tent sheet is attached to the edge of the case through a seal element, and the frame pipes are fastened at predetermined inner surface positions of the tent sheet.
