Claims

[Scope of Claim for Utility Model Registration] 1. Providing a joint of different diameters that can connect one of a large-diameter pipe and a small-diameter pipe with different diameters to a pipe of a predetermined diameter,
This different diameter joint is a pipe joint characterized in that it has a male thread that can be screwed together with a large diameter female thread, and a female thread that can be screwed together with a small diameter male thread. 2. The pipe joint according to claim 1 of the utility model registration claim, wherein the female thread and the male thread of the different diameter joint are formed on the same side, and on the opposite side, a connecting part for fitting a pipe of a predetermined diameter is formed. 3. The pipe joint according to claim 1, wherein the male thread of the different diameter joint is formed so that it can be screwed to the female thread of the large diameter joint. 4. The pipe joint according to claim 3, which is a utility model registration, wherein female threads that can be screwed to the male threads of the large diameter pipe are formed on both sides of the large diameter joint.
