A joint (10) connecting with a pipe (95) and having: a first member (11); a second member (12), which is screwed to the first member; and a ferrule (13) disposed in a housing space (15) formed by the inner peripheral surface of the first member, the inner peripheral surface of the second member, and the outer peripheral surface of the pipe. The ferrule comprises: a rising part (13c) including a first end part (13a); a pressed part (13d), located further toward the second end part (13b) than the rising part; and an intermediate part (13e) including a portion having a larger inner diameter than the first end part and the second end part, and connecting the rising part and the pressed part. The first member comprises a first tapered inner peripheral surface (11a), which is a tapered inner peripheral surface in contact with the first end part of the ferrule. The second member comprises a pressing part (12a), which presses at least a part of the pressed part of the ferrule. The housing space comprises a first allowance space (15a), which is capable of housing the ferrule and lifting the rising part so as to increase the angle with respect to the outer peripheral surface of the pipe. |
