PROBLEM TO BE SOLVED: To promote the high strength, weak thickness and weight reduction of a bag main body, and to economically eliminate a forcible weak point of the bag main body.SOLUTION: A bag-type jack comprises a rubber-made bag main body 10 having a first support face 10a and a second support face 10b, and a plurality of reinforcing gripping sheets 20A, 20B which are embedded into the bag main body 10. The reinforcing gripping sheets 20A, 20B are obtained by cylindrically forming high-strength fibers, a plurality of the reinforcing gripping sheets are arranged while crossing each other so as to surround an internal space of the bag main body 10 from a different direction, and the reinforcing gripping sheets 20A, 20B are laminated in a crossing manner by the first support face 10a, and the second support face 10b.
【課題】バッグ本体の高強度化、薄肉化、および軽量化を図るとともに、バッグ本体の強度的弱点を経済的に解消すること。【解決手段】第1支持面10aと第2支持面10bを有するゴム製のバッグ本体10と、バッグ本体10に埋設する補強用の複数の補強抱持シート20A,20Bとを具備し、補強抱持シート20A,20Bは高強度繊維を筒状に形成してなり、バッグ本体10の内部空間を異方向から包囲するように、複数の補強抱持シートを交差させて配置して、第1支持面10aおよび第2支持面10bで補強抱持シート20A,20Bを交差して積層させた。【選択図】図1
