Claims

[Claims for Utility Model Registration] The outer cylinder and the inner cylinder are coaxial and substantially horizontal, and the inner cylinder is extended beyond the terminal edge of the outer cylinder, and an air supply path is provided between the outer cylinder and the inner cylinder. The terminal edge of the inner cylinder is closed, and an exhaust hole is provided on the outer periphery near the terminal edge of the inner cylinder, so that the inner cylinder forms an exhaust path and guides the exhaust flow and converts the exhaust flow into a supply air flow. In the supply/exhaust pipe of a combustion device, which is provided with an exhaust flange on the outer periphery of the inner cylinder between the disposed part of the exhaust hole and the terminal edge of the outer cylinder, and is installed with each terminal edge side facing outdoors, An air supply and exhaust pipe for a combustion device, characterized in that the positions of the exhaust hole and the exhaust flange are set such that adjacent parts of the exhaust hole and the exhaust flange have a predetermined interval in the horizontal direction from each other.
