A pipe joint structure includes a pipe with a collar projecting radially, and a flange having a pipe insertion hole formed through an end of the pipe and a flange recessed portion provided at a circumferential portion of the pipe insertion hole and formed to receive the collar. An inner diameter of the flange recessed portion is greater than an outer diameter of the collar, and the collar is plastically deformed in a radial direction to bring the collar into surface contact with an inner surface of the flange recessed portion. The pipe and the flange may be connected to each other securely, and the cost for the manufacture may be significantly reduced.
