    • PROBLEM TO BE SOLVED: To provide a hose coupling which can be manufactured by relatively simple processing and can be made compact in the radial direction as easily as possible.SOLUTION: The hose coupling includes: a nipple member 1 having a tip 2 to which a hose can be connected; an intermediate member 6 having one end 7 connectable to an apparatus side and the other end 8 externally fitted to a base end 3 of the nipple member 1; and a socket member 12 interconnecting the base end 3 of the nipple member 1 and the other end 8 of the intermediate member 6 so as to enable relative rotation around an axis X. The socket member 12 includes: a first portion 12A externally fitted to the other end 8 of the intermediate member 6; and a second portion 12B which is extended from part of the first portion 12A to the radial inner side and through which only the tip 2 of the nipple member 1 is inserted freely. The outer periphery of the other end 8 of the intermediate member 6 includes a coming-off prevention recess 9 to which part of the first portion 12A is engageably inserted inwardly in the radial direction.
    • 要解决的问题:提供可以通过相对简单的处理制造的软管接头,并且可以尽可能容易地在径向方向上紧凑化。 解决方案:软管接头包括:具有尖端2的接头构件1,软管可连接到端头2; 中间构件6,其一端7可连接到装置侧,另一端8外部装配到接头构件1的基端3; 以及将乳头构件1的基端3与中间构件6的另一端8连接起来以使得能够围绕轴线X相对旋转的插座构件12.插座构件12包括:第一部分12A,外部安装到 中间构件6的另一端8; 以及第二部分12B,其从第一部分12A的一部分延伸到径向内侧,并且仅使乳头构件1的末端2自由地插入。 中间构件6的另一端8的外周包括防脱凹槽9,其中第一部分12A的一部分在径向方向上可向内插入其中。 版权所有(C)2013,JPO&INPIT
