ABSTRACT:
A guard for a power transmission shaft such as a tractor pto shaft 18,20 comprises a flexible convoluted tubing 24 with end couplings 26 which together totally enclose the rotating parts.

A tube 34 journalled on bearings 36, or equivalent bearing means, prevents damage to the tubing 24 by the shaft 18,20.
