In the tent, the tent contains a sheet, supports, in which upper end sections are engaged at a plurality of places of the outer periphery of the sheet, lower-end leg sections are placed on a ground surface and the sheet is positioned in a fixed space from the ground surface, and ropes stretched towards the external direction of the sheet from the engaging sections of the sheet and the supports, and the lower-end leg sections of the supports are divided into the plural and placed on the ground surface. Thus, the supports can be disposed in upright stably as compared to one leg sections of the supports. The sheet supported by the supports is stabilized because of the stable supports. Since the sheet is supported by a supporting tool at approximately the center of the sheet is supported, the downwards recessing of a section in the vicinity of the central section of the sheet can be prevented.
