PROBLEM TO BE SOLVED: To provide a joint capable of effectively suppressing stagnation of water in a branch pipe portion.SOLUTION: A joint includes a main pipe portion 10, and a branch pipe portion 20 branched from the main pipe portion. In a pipe conduit of the joint, a partitioning portion 30 is disposed to divide a flow channel, and by an inner wall surface of the joint and the partitioning portion, a main flow channel MF for guiding a fluid from a first pipe end side 10a of the main pipe portion to a second pipe end side 10b of the main pipe portion in the main pipe portion, a first branch flow channel BF1 for guiding the fluid not entering the main flow channel, of the fluid from the first pipe end side, to a tip side of the branch pipe portion, and a second branch flow channel BF2 for joining the fluid from the tip side of the branch pipe portion to the fluid from the main flow channel are respectively defined. The first branch flow channel has a cross-sectional area which is at least partially gradually reduced toward the tip side of the branch pipe portion.SELECTED DRAWING: Figure 3 |
