Abstract:
1. A connector, to which a pipe having an annular flange part on an outer perimeter surface is connected, comprising: a connector body having a circular opening part in which said pipe is inserted, and a coupling-accepting part formed thereon; and a confirmation member arranged on said connector body, and including a lock mechanism locking the confirmation member to said connector body and an urging member unlocking the lock mechanism from the connector body, the lock mechanism including a leg piece disposed in the connector body, a pressing part formed on an end part of said leg piece and positioned at an outside of said urging member, and a coupling part formed on the end part of said leg piece and coupling with the coupling-accepting part, the urging member including an elastic piece extending adjacent to said leg piece and protruding inwardly toward said opening part from an outside of said connector body, wherein the confirmation member moves between a standby position where the flange part of said pipe passes through said opening part, and a connected position where the confirmation member moves in a radial direction of said opening part such that said pipe is connected at a prescribed position; when said pipe is inserted in the opening part, the elastic piece of the urging member is pushed to spread outward and presses the pressing part of the lock mechanism to unlock said confirmation member locked by said lock mechanism, and when said flange part contacts the elastic piece, the elastic piece turns inwardly along the outer perimeter surface of said flange part to move said confirmation member to said connected position while releasing urging forces accumulated in the leg piece and the elastic piece to return shapes thereof.
