<p><P>PROBLEM TO BE SOLVED: To securely seal a hose and an insert pipe with by suitably reducing a diameter of a sleeve. <P>SOLUTION: An annular recess 4 extending in a peripheral direction is formed along the outer peripheral surface 1a of the insert pipe 1, an annular seal material 5 elastically deformable is fitted in the annular recess 4, and held to be immovable in the axial direction, and the outer peripheral end of the annular seal material 5 is protruded from the outer peripheral surface 1a of the insert pipe 1, and pressure-contacts with the inner peripheral surface H1 of the hose H, and thereby, the hose inner peripheral surface H1 confronting a reduced diameter part 2a' is strongly pressed to the annular seal material 5 protruded from the outer peripheral surface 1a of the insert pipe 1 when the diameter of a sleeve outer cylindrical part 2a is reduced, and the hose inner peripheral surface H1 and the annular seal material 5 are strongly adhered to each other. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
