<P>PROBLEM TO BE SOLVED: To maintain excellent sealing performance by limiting diameter reduction of a first piping with a reinforcing panel which is mounted on an inner circumference face of the first piping. <P>SOLUTION: In the pipe connection structure, a sealing ring 60 is attached on an outer circumference face of the first piping (hose) 10 along a circumference direction and the hose 10 to which the sealing ring 60 is attached is inserted in a pipe 50. A clearance between the outer circumference face of the hose 10 and an inner circumference face of the pipe 50 is to be sealed by the sealing ring 60. On the inner circumference face of the hose 10, the reinforcing panel 70 in a collar shape is attached to limit displacement of the hose 10 in a diameter-reduction direction in accordance with fastening by the sealing ring 60 by contacting with the inner circumference face along the circumference direction. The reinforcing panel 70 is formed by bending a band-like flat spring material as a circle and is always energized in a diameter-enlargement direction and elastically pressed against the inner circumference face of the hose 10. <P>COPYRIGHT: (C)2007,JPO&INPIT |
