ABSTRACT:
In a connecting structure of a pipe of an air conditioning unit and a pipe joint for supporting the pipe, an insertion hole through which the pipe is inserted is formed within the pipe joint. The insertion hole has substantially a L-shaped cross-section and includes a first portion for receiving an end portion of the pipe and a second portion for receiving a flat portion of the pipe. The second portion is elliptical-shaped. In connecting the pipe to the pipe joint, the pipe is pressed into the insertion hole by a pressing punch. As a result, the pipe is bent and shaped along the elliptical shape of the second portion in the pipe joint, thereby forming the flat portion in the bend of the pipe. At the same time that the flat portion is formed, the pipe is clamped in the pipe joint.
