特徴とするダクトの接続構造。 In a duct connection structure in which both ducts are connected by inserting the ends of the ducts to be connected to each other into both ends of a joint, the joint has an external dimension slightly smaller than an internal dimension of the duct. A cylindrical locking part whose inner dimension is larger than the outer dimension of the main body is provided on the outside of the central part in the longitudinal direction of the cylindrical main body, and the inner surface of the locking part and A sealing material is disposed around the entire circumference between the outer surface of the main body part, and a locking edge is formed in the locking part by bending both ends diagonally inward. On the other hand, the end of the duct to be connected is provided with a locking claw that projects diagonally outward from the tip side of the duct toward the rear side, and the end of the duct is connected to the end of the main body of the joint. By inserting the duct outward, the locking claw of the duct is engaged with the locking edge formed on the locking portion of the joint, and the tip of the duct is buried in the sealing material. A duct connection structure characterized by:
