PROBLEM TO BE SOLVED: To provide a flared joint for fixing a plurality of types of different diameter connection pipes with a change of a bush only instead of a flared joint body and a flared nut by providing thickness different bushes in an inner diameter portion of the flared nut for alternatively connecting the different diameter connection pipe and alternatively connecting the plurality of different diameter connection pipes, while reducing the quantity of stock and cost and securing sufficient pressure-proofing performance. SOLUTION: The flared joint, whose flared joint body 1 has a tapered outer face portion 5 to which the connection pipe 22 is connected and fixed and a screw portion 7 formed on the outer periphery, comprises the flared nut 2 to be fastened to the screw portion 7, and the cylindrical bush 3 to be arranged in the inner diameter portion of the flared nut 2. With the bush 3 arranged or not or the different thickness bush arranged, the plurality of different diameter connection pipes 22 are alternatively connected to the tapered outer face portion 5.
