PROBLEM TO BE SOLVED: To provide a piping connection structure that can absorb relative displacement in a horizontal direction while maintaining pressure resistance and watertightness as piping. SOLUTION: The piping connection structure 10 includes a first metal ring 11 and a second metal ring 12 relatively slidable by a structure (a separating structure) in which the first metal ring 11 and second metal ring 12 are separated with clearances 14. As a result, the first metal rings 11 are mutually slidable by maximum about 100 mm (two parts of the clearance 14). Since the piping connection structure 10 is a laminated structure, if there are 11 layers (10 sliding parts), for instance, relative horizontal displacement of maximum 1,000 mm (1 m) can be absorbed.
