PROBLEM TO BE SOLVED: To provide a different diameter hose coupling capable of connecting different diameter hoses to each other by the small number of component elements while preventing dew condensation effectively.SOLUTION: This invention relates to a different diameter hose coupling 10 for use in connecting two or more hoses of different diameters that comprises a hollow part and two end openings (the first end opening 1a and the second end opening 1b) communicated with the hollow part. The coupling comprises a first fixing part 2 and a second fixing part 3 to which each of the end parts of the first hose H1 and the second hose H2 of different diameters that are inserted from the first end opening 1a into the hollow part, and the third fixing part 5 to which the end part of the third hose H3 inserted from the second end opening 1b into the hollow part is fixed is set at a position different from the first fixing part 2 and the second fixing part 3. |
