Abstract
A U-joint construction includes a drive coupling member connected to a drive shaft, and intermediate coupling member, and a driven coupling member connected to a driven shaft. The drive coupling member and the driven coupling member include bearings which protrude within channels of the intermediate coupling member. The drive bearing and the driven bearing are each pivotal about two axes, one of which coincides with the longitudinal axes of the channel and the other which is transverse with respect thereto. According to one embodiment of the invention the first and second bearings are also longitudinally slidable within the channels.
