Abstract
A ring member and ring members made of metal are tightened and installed to the outer circumferential surface of a body made of a resin material. Accordingly, the body is prevented from outward deformation. When a tube joint is used in a high temperature atmosphere, even if any force acts on a fluid tube in the direction to cause detachment from the tube joint due to any external force or the pressure fluid flowing through the inside of the tube joint, then the fluid tube and a connecting member inserted into the body are reliably prevented from disengagement.
Claims6
A tube joint comprising;
- a body made of a resin material having a distal edge and an opening at a second end of said body;
- an attachment/detachment mechanism into which a tube is configured to be inserted and which comprises:
- a fastening section biting an outer circumferential surface of the tube;
- and
- an engaging member provided outside said fastening section, said engaging member having a projection which outwardly projects from an outer circumferential surface of said engaging member and which engages with an inner circumferential wall surface of said body at said second end;
- and
- a ring member fitted to an outer circumferential wall surface of said body at said second end,
- wherein said projection of said engaging member is positioned between the distal edge of the body and said fastening section, and wherein said ring member is positioned between the distal edge of the body and said projection of said engaging member.
