Rowenta Va200 fan oscillation axis replacement

We have a fan which oscillation axis broke. I think that is because of fatigue https://en.wikipedia.org/wiki/Fatigue_(material). The place where it broke does have has a change of section, which is prone to fatigue breaks. Another reason could be mechanical blockage, so It broke in the weaker part. A kind of mechanical fuse should be added to avoid uncontrolled damage.

This model is made in china, and probably is rebranded, so is possible that your model has the same axle or very similar.
