<P>PROBLEM TO BE SOLVED: To provide a pipe connection structure of a pipe connection part, a wiring box, and a pipe joint for forming a connection using a methods for connecting corrugated pipes with different pipe diameters in different manners and facilitating a connection work. <P>SOLUTION: The pipe connections 20 are provided on an upper wall 12a and a lower wall 12b of the wiring box 11, and include pipe insertion sections 30 having pipe insertion openings 31a. An end of the corrugated pipe 10 can be inserted into the pipe insertion section 30 from the pipe insertion opening 31a in the central axial direction of the pipe insertion section 30. An elastic and deformable engagement pawl 35 is formed in the pipe insertion section 30, and engaged with a recess stripe on the large diameter corrugated pipe 10B. Insertion holes 18 as holes smaller than the pipe insertion openings 31a are provided at the pipe insertion sections 30 on the back side behind the engagement pawls 35 in the insertion direction of the corrugated pipe 10. An engagement protrusion 18a is formed on an inner circumference of the insertion hole 18, and engaged with a recess stripe 10b of the small diameter corrugated pipe 10A having a diameter smaller than the large diameter corrugated pipe 10B. <P>COPYRIGHT: (C)2007,JPO&INPIT |
