<P>PROBLEM TO BE SOLVED: To provide a connecting structure of a flexible hose and a mouth member which has strength and airtightness or liquid tightness in spite of being compact in size, and to provide a method of manufacturing the same. <P>SOLUTION: In a hose end connecting structure in which the end 2a of a hose body 2 having spiral or ring-shaped projections 21 on outer circumferential surface thereof is connected to the mouth member 1 which is injection-molded into such a shape that covers the outer circumferential surface of at least the end of the hose body and integrated to the hose body, the structure connects the hose body end 2a to the mouth member 1 in a compressed state in the hose axial direction so that distances P2 of the projections 21 at the hose body end 2a covered by the mouth member 1 become shorter than distances P1 of the projections 21 in the no-load state of the hose body 2. When recessed grooves 22 are formed on the inner circumferential surface of the hose, it is desirable to compress the hose end 2a to such an extent as to block the recessed grooves. <P>COPYRIGHT: (C)2012,JPO&INPIT |
