Abstract: In a flareless-type pipe joint, a pressing surface, which presses a rear end portion of a ferrule in the axial direction and toward the inner periphery of the ferrule, is formed in a joint body or a coupling member in which a cam surface is not formed. The ferrule has a groove that extends radially outward from the inner periphery. By pressing the rear end portion in the axial direction and toward the inner periphery by the pressing surface, the distal portion of the ferrule is pressed against the cam surface and an edge portion of the distal portion is deformed to bite into a pipe. An edge portion of a rear end portion of the inner peripheral surface of the ferrule is deformed to bite into the pipe.

Abstract: In a flareless-type pipe joint, a pressing surface 25, which presses a rear end portion of a ferrule 3 in the axial direction and toward the inner periphery of the ferrule 3, is formed in a joint body 1 or a coupling member 2 in which a cam surface 19 is not formed. The ferrule 3 has a groove 36 that extends radially outward from the inner periphery. By pressing the rear end portion in the axial direction and toward the inner periphery by means of the pressing surface 25, the distal portion of the ferrule 3 is pressed against the cam surface 19 and an edge portion 3b of the distal portion is deformed to bite into a pipe p. Further, an edge portion 3c of a rear end portion of the inner peripheral surface of the ferrule 3 is deformed to bite into the pipe p.
