<p>PROBLEM TO BE SOLVED: To easily and firmly connect a connecting end of an individually formed hose to an inserting pipe part. SOLUTION: In a tip part 10a of a hose 1, the outer peripheral surface is coaxially polished and formed into a circular shape, an annular cylindrical member 12 is fitted and fixed to a hose by adhesives. The hose is pressed around the inserting pipe part 20 until the tip of the annular cylindrical part fitted around the hose is brought in contact with the side surface of a stopper 21. The hose tends to extend in the radial direction by being pressed by the pipe, however, the extension in the radial direction of the hose is stopped by the annular cylindrical member fitted around the outer periphery. Therefore, fastening of the hose in relation to a pipe is relatively strengthened, drawing resistance and sealing performance of the connecting structure are enhanced to the degree of fitting caulking connection, and the connecting structure is provided at low cost equal to clamp fastening. Detachment of the connecting part by a user can be prevented by fitting the annular cylindrical member, and reliability of the connecting structure is maintained.</p> |
