したりすることが行なわれている。A conventional umbrella rib is made up of a main rib and a coronal rib that extend radially from the grassland centering on the chrysanthemum, and a bridge that is connected to the middle part of the main rib and the lower wheel. These materials are generally made of hard steel, polished special steel strips, stainless steel, etc., and the surfaces are coated with various paints or are plated with various metals to prevent rust or improve appearance. things are being done.

合成樹脂又は強化合成樹脂からなる傘骨である。The present inventor has been studying the development of new uses for such new plastic materials and has discovered that a synthetic resin material having a specific physical property E has extremely favorable usage characteristics as a constituent material of the umbrella rib, and has accomplished the present invention. reached. That is, the object of the present invention is to provide an umbrella rib that has superior mechanical strength and durability, is easy to manufacture, and has good usability characteristics compared to conventional metal umbrella ribs, and has excellent bending elasticity. Rate 20.
The umbrella rib is made of synthetic resin or reinforced synthetic resin having physical property values of 000 mm/- or more, tensile strength of 4001 (2/- or more), and impact strength of 5 Kf·tm/cm or more.

骨の構成材料として使用するときは従来の金Ｗ４製傘骨
に比し、次に列制するような顕著な効果が得られる。When using the above-mentioned ilU synthetic resin or the reinforced liquid-forming side layer as the constituent material of the umbrella rib, a remarkable effect that is second to none can be obtained compared to the conventional umbrella rib made of gold W4.
１）これらの合成樹脂材料は比重が２以下で小さる。1) These synthetic resin materials have a small specific gravity of 2 or less.
３）永久に銹ひることがない。3) It will never rust.
４）成型が容易で、金属製では不ｏＪ能であった複数の
連結部をも一体成型口丁能であり計度性がある。4) It is easy to mold, and it is possible to integrally mold a plurality of connecting parts, which would be impossible with metal, and it is easy to measure.
