<p>PROBLEM TO BE SOLVED: To provide a hose connection structure which can securely prevent detachment of a hose.SOLUTION: A hose connection structure includes a pipe joint 10, a sleeve 20 coaxially arranged on an outer circumference side of the pipe joint, and a reinforcement yarn layer 33, and is provided with an elastically deformable hose 30 which is sandwiched between the pipe joint and the sleeve in a radial direction. The pipe joint includes an annular groove 12. When an axial position of the sleeve corresponding to the annular groove is caulked inward in the diameter direction in a state that the hose is inserted between the pipe joint and the sleeve in the radial direction, the hose is compressed by an inwardly projecting part of the sleeve in an axial direction position and a bottom part of the annular groove. A caulking rate A is 25-50%.</p> |
