<P>PROBLEM TO BE SOLVED: To provide a piping connector structure for connecting cooling medium piping members together, having reduced costs and preventing the entry of water and foreign matters from the outside by improving sealing performance. <P>SOLUTION: A first piping member 2 and a second piping member 3 are formed adaptably to abut on each other at a taper outer face 25 and at a taper inner face 323, respectively. When the first piping member 2 is inserted into the second piping member 3 with a spring joint 4 fitted into a fitting face 324 formed on the reverse of a large diameter portion 322 of the second piping member 3, a plate spring bent portion of the spring joint 4 can be flexible in the direction of enlarging the diameter. When the taper outer face 25 and the taper inner face 323 abut on each other, the spring joint 4 thrusts an engagement face 26 of the first piping member 2 to press the taper outer face 25 against the taper inner face 323, thereby preventing the looseness and improving the sealing performance. <P>COPYRIGHT: (C)2004,JPO |
