<P>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. <P>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. <P>COPYRIGHT: (C)2013,JPO&INPIT |
