<p>PROBLEM TO BE SOLVED: To provide a drain pipe joint provided with a horizontal branch pipe connection part capable of giving the turning property to vertical drain water from above even if a guide wall for flowing horizontal drain water from a horizontal branch pipe with eccentricity protrudes on an inner peripheral face of a barrel part. SOLUTION: This drain pipe joint 10 is provided with upper and lower vertical pipe connection parts 11, 15 and a horizontal branch pipe connection part 22 connectable with a horizontal branch pipe 4. A downstream side of a flow passage 28 for horizontal drain water WH flowing from the horizontal branch pipe connection part 22 is directed obliquely and downward to the left so that horizontal drain water can turn to the left and flow down along an inner peripheral face 20a of a barrel part 20. A guide wall 30 guiding the horizontal drain water WH protrudes at a peripheral fringe on an upper side of an opening 27 on an inner peripheral face 20a side of the barrel part in a horizontal drain passage. A turn guide inclined face 33a inclined downward to the left is formed on an upper face 31b side of the guide wall 30 so as to give the turning property to vertical drain water WV from above so that the vertical drain water WV turns to the left and flows down.</p> |
