Title:
PIPE JOINT
Document Type and Number:
Japanese Patent JP3678515
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To positively display slip-off preventing function by forming a pipe body slip-off preventing edge at the inward face of a pressing member, and forming a pressing member storage part in an inner collar in such structure that the pressing member can be radially enlarged/contracted in diameter while being prevented from slipping out onto the pipe body side.
SOLUTION: In case of a pipe body 40 being slightly inserted into an inner collar 8, the tip of the pipe body 40 comes in contact with a step part 2, so that the position of the pipe body 40 is determined. In case of applying force to pull out the pipe body from this state, a pressing member 9 is pressed to the taper part 11 side of an outer collar 10 by the resilience of a coil spring 7, and the surface of the pipe body 40 is pressed by the edge of the pressing member 9 by the taper part 11 of the outer collar 10. The pipe body is therefore hindered from being pulled out of a pipe joint.
