A universal joint between the ends of two shafts is enclosed by a protective guard assembly comprising rotatably mounted boots of a resilient elastic material extending over the joint from the ends of the shafts. An annular member overlaps a portion of each of the boots and has a supporting ring which extends radially between the ends of the boots. The guard member may be positioned on the inner or outer surfaces of the boots and the support ring respectively extends radially outwardly or radially inwardly between the boot ends. |
