Claims

[Claims for Utility Model Registration] (1) A packing chamber is provided on the inner surface of the end of the joint body into which the pipe to be connected is inserted, and a packing made of an elastic material is attached to the packing chamber and engaged with the joint body. The seal is pressed through the pressing member, and a ring chamber formed in the pressing member and having an inner circumferential tapered surface that expands toward the pressing side is provided with a substantially annular shape with a cutout at one point on the circumference on the inner peripheral side. 1. A pipe joint equipped with a biting ring having a plurality of biting protrusions, characterized in that the inner peripheral diameters of the inner tips of the biting protrusions are set to two different groups of inner circumferential diameters. (2) In the utility model registration claim 1, the outer periphery of the biting ring has a gap between the circumferential portion that engages with the inner tapered surface of the pressing member and the inner tapered surface. A pipe joint consisting of a reduced diameter section. (3) Scope of claims for utility model registration, paragraph 1 or 2
2. The pipe joint according to item 1, wherein the biting protrusions on the smaller inner diameter side of the second group have an acute-angled shape that bites into the pipe more easily than the biting protrusions on the larger diameter side.
