ABSTRACT:
An improved guard for an articulated torque transmitting shaft such as the power transmission shaft connecting a tractor with an agricultural implement is disclosed. The guard according to the invention comprises bellows members for fitting over U-joints at either end and telescoping tubes connecting the bellows. The telescoping tubes are locked to the respective bellows by L-shaped keys which extend through slots formed through the tube and through the bellows and which have circumferentially extending tabs which ride in grooves formed in the universal joints, to locate the juncture of the tube and bellows with respect to the joint. In the preferred embodiment, the entire assembly is constructed of plastic.
