The prop is formed of metal or wood, the metal or wood umbrella which is radially coupled to the prop, and is connected to the umbrella. A cover cloth formed of a waterproof cloth or a fat or oil is provided.

When the umbrella is folded, its length is relatively long and heavy, and it is not convenient to carry, and there is a problem in that the prop and umbrella flesh are easily rusted when made of steel, and easily broken when made of wood.

Recently, in consideration of such a problem, a folding umbrella that can be folded in two or three stages using a stainless steel, such as excellent corrosion resistance has been widely used.

However, in such a conventional umbrella, the support and the flesh are made of a metal member, which is not only heavy, but also the structure is complicated as the support and the flesh can be folded in two or three stages. It has the disadvantage of being added. In addition, such a conventional umbrella is reduced in length by being folded in the longitudinal direction, while being relatively larger in the width direction, there is a limit in reducing the volume and weight below a certain level, so that the bulkiness and rigidity when carrying still cause inconvenience. There is a problem.

Accordingly, an object of the present invention is to provide an air-injectable umbrella that is light and easy to carry and can reduce volume during exhaust.
