JOINT OF HOSE

摘要

PROBLEM TO BE SOLVED: To provide a joint capable of easily and quickly jointing a joint and a hose and of keeping a sure joint state with preventing joint's falling off or water leak even if a ring is distorted a little bit during jointing at a fire scene in a large scale fire or the like. SOLUTION: A bulging out part 3 including a tapered surface 3a gradually expanding outer diameter toward an end of a tube part 2 and a cylindrical surface 3b connected to the maximum diameter part of the tapered surface 3a is formed on an end part outer circumference of the rigid and straight tube part 2 having a roughly same outer diameter as an inner diameter of the hose 4. The ring 5 is fitted on an outside of the tube part 2. A tapered surface 5a fitting to the tapered surface 3a of the bulging out part 3 and a cylindrical surface 5b formed in connection to the maximum diameter part of the tapered surface 5a and fitted on outside of the cylindrical surface 3b of the bulging out part 3 are formed on an inner surface of the ring 5.
