ᐅ Replacement part for the drain under the sink: stopper won’t lift up

Good day!

Does anyone know the name of the part marked in red in the photo? It is usually located where the arrow points. It is used to lift or lower the plug. The rest of the rod, the part before the white ball, has completely rotted away and is missing. Because of this, the plug can no longer be moved. I would be fine with just that rod with the white ball. The whole assembly is under a bathroom vanity from the "Virto" series by Keramag, manufactured in 1999.

Thanks, Matthias!

Try using the term eccentric rod.

Take a look – that's exactly it! I would never have thought of that. Many thanks from Matthias!

Just as a side note: if the chrome pipes are already rusting on the outside, you should replace the entire siphon. You can expect it to start leaking any day. I have already replaced two of them in my home after 18 years.
