PROBLEM TO BE SOLVED: To provide a pipe attachment structure which enables removal of a pipe from a hollow member and easy assembly of the pipe.SOLUTION: In an attachment structure of a pipe 40, the pipe 40 is inserted into a pipe attachment member 20 to be attached. The pipe attachment member 20 has an attachment flange part 23, a pipe attachment cylinder part 21, and a tank inner cylinder part 22. A seal member 30 is provided between the pipe attachment member 20 and a pipe tip part 41 provided at a tip of the pipe 40 and attached to the pipe attachment member 20. The seal member 30 has a seal cylinder part 31 and a seal engagement part 33. The seal cylinder part 31 is sandwiched between the pipe tip part 41 and the pipe attachment cylinder part 21. The seal engagement part 33 holds the pipe tip part 41 to attach the pipe 40 to the hollow member.SELECTED DRAWING: Figure 1
