ABSTRACT:
A helicoid thread mechanism which comprises a male helically threaded tube and a female helically threaded tube is provided with a helically threaded block for threadedly engaging the female tube onto the male tube. A sliding frictional contact noise which is produced between the two tube members when they engage with each other is eliminated by suitable selection on the helically threaded shape and the material of the block.
