PROBLEM TO BE SOLVED: To provide a T-shaped pipe joint with good appearance, which enables branching connection of down pipes in such a manner as to make a joint inconspicuous by improving the appearance of the joint, and which does not cause an increase in manufacturing cost. SOLUTION: In this T-shaped pipe joint to which first, second and third cover members are externally fitted and attached, convex protrusions, which enable assembly in such a manner that central positions are aligned with one another, are formed in a strip shape on an inside-diameter surface of each cover member; first, second and third T-shaped insertion portions of a core component are coated with an adhesive, and fitted and joined to a perpendicular surface and a semicircular surface at the end of each cover member via an inclined plane; the down pipe having a contracted pipe portion coated with the adhesive is fitted, inserted and joined to the first insertion opening of the first cover member; the second cover member is fitted, inserted and attached to a T-shape of the core component; a contracted pipe portion coated with the adhesive is formed into the second insertion opening; the end of the down pipe is fitted, inserted and joined thereto; and the down pipe having a contracted pipe portion coated with the adhesive is fitted, inserted and joined to the third insertion opening of the third cover member. The T-shaped pipe joint is provided with a joint structure described above. COPYRIGHT: (C)2011,JPO&INPIT
