Title:
FEMALE PIPE JOINT MEMBER
Document Type and Number:
Japanese Patent JP2018204703
Kind Code:
A
Abstract:
To provide a female pipe joint member which can increase a range of a dimensional tolerance of a male pipe joint member that can be appropriately connected.SOLUTION: A lock part 22, a first restriction member 26, and a second restriction member 30 are retained on a female pipe joint body 10. The second restriction member is positioned frontward shifted from the first restriction member, and has a diameter larger than that of the first restriction member. When a pipe 80 having a relatively large outer diameter is inserted into a flow passage 16, a sleeve 34 displaces to a first connecting position, and the first restriction member 26 is retained in a restriction position by a restriction member retaining face 48 of the sleeve to be engaged with an outer peripheral face 86 of the pipe. When a pipe 80 having a relatively small outer diameter is inserted, a sleeve 34 displaces to a further-forward second connecting position, and the second restriction member 30 is retained in a restriction position by a restriction member retaining face to be engaged with an outer peripheral face 86 of the pipe. When the sleeve 34 is in a first or second connecting position, the lock part 22 is retained in a locking position by a lock part retaining face 46 of the sleeve to lock a locking projection 82 of the pipe.SELECTED DRAWING: Figure 3
