PURPOSE: A simple awning curtain is provided which is easily carried and installed, supplied at a low price and promotes the value as merchandise by using an elastic tube member instead of a pole as well as a low-priced shade curtain. CONSTITUTION: A simple awning curtain (10) comprises a tube frame member unfolded/folded by the intake/exhaust of air and a shade installed on the upper side of a tube frame member to intercept sunshine. The tube frame member comprises a base tube frame (12) contacted to the ground by intakinging air through an air opening (22) using a portable air pump, an obtuse angle tube frame (14) connected to the both ends of the base tube frame (12) and unfolded at an obtuse angle with the base tube frame (12), an intermediate tube frame (16) slanted horizontally at regular intervals from the both ends of the obtuse angle tube frame (14) and connected to the base tube frame (12) between the base tube frame (12) and the obtuse angle tube frame (14) and forming an arc with the top end of a base and the obtuse angle tube frame when unfolded. A string (22) of regular length connects the both ends of the base tube frame (12) to prevent the both ends of the base tube frame (12) from moving to be slant over one another when intaking air by an air pump. Attaching a net (20) on the side of a shading curtain (18) to ventilate easily and using an air mat (26) provides comfort and repose to users.
