PROBLEM TO BE SOLVED: To provide a different-diameter-pipe joint device capable of connecting different-diameter pipes to each other while absorbing the dispersion of the inner and outer diameters thereof. SOLUTION: This different-diameter-pipe joint device for connecting a steel pipe 1 to a soft pipe 2 with different outer and inner diameters comprises a joint body 10 formed of a thin-wall metal material and a tightening members 20A and 20B. The joint body 10 comprises a first connection part 11 fitted to the outer peripheral surface of the steel pipe 1 and a connection part 15 fitted to the inner peripheral surface of the soft pipe 2. Two slits 12 and 12 are formed in the first connection part 11. The outer peripheral surface of the first connection part 11 fitted to the steep pipe 1 is tightened by a tightening member 20A, and the outer peripheral surface of the soft pipe 2 fitted to the second connection part 15 is tightened by a tightening member 20B.
