Abstract

A fitting includes: a first member; a second member coupled by screw coupling with the first member; and a ferrule placed in an accommodation space between the first member, the second member, and a pipe. The ferrule has a rising portion including a first end portion, a pressed portion located closer to a second end portion than the rising portion, and an intermediate portion including a portion where an inner diameter is greater than the first end portion and the second end portion, the intermediate portion connecting together the rising portion and the pressed portion. The first member has a first tapered inner circumferential surface, which is an inner circumferential surface having a tapered shape, to be in contact with the first end portion of the ferrule. The second member has a pressing portion for pressing at least a portion of the pressed portion of the ferrule. The accommodation space provides a clearance for accommodating the ferrule and allowing the rising portion to rise so as to increase an angle of the rising portion.
