PROBLEM TO BE SOLVED: To provide an inexpensive, compact and durable fire-fighting swivel joint.SOLUTION: A fire-fighting swivel joint comprises a C-shaped storage ring made of an elastic material, a male joint having a first peripheral groove capable of totally storing the storage ring on the outer peripheral surface of a connection part, and a female joint having a second peripheral groove capable of storing more than half of the outer periphery of the storage ring on an inner peripheral surface of the connection part. The male and female joints are engaged with each other in a state of the first peripheral groove and the second peripheral groove being facingly disposed on a same axial position, and the storage ring is stored in an elastically energized state in a facing space of the first peripheral groove and the second peripheral groove.SELECTED DRAWING: Figure 1
【課題】安価でコンパクトかつ耐久性を有する自由回転構造を備える消防用自由回転継手を提供すること。【解決手段】弾性材からなるＣ字形状の収納リングと、前記収納リングを全収納可能な第一周溝を接続部の外周面に有する雄継手と、前記収納リングの外周過半部を収納可能な第二周溝を接続部の内周面に有する雌継手と、を具備して構成され、前記第一周溝及び前記第二周溝が同一軸方向位置に対向配置された状態で雄雌継手が嵌合し、かつ、前記第一周溝及び前記第二周溝の対向空間内に前記収納リングが弾性付勢状態で収納されてなる消防用自由回転継手。【選択図】図１
