Abstract
A universal joint includes a pair of yokes each having two trunnions projecting radially thereof, and an annular intermediate ring having bearings arranged on two diametrical lines thereof intersecting each other at right angles for supporting the respective trunnions. An annular central cover having a spherical outer surface is fixedly intimately fitted around the intermediate ring. Between the ring and a connecting flange at the outer end of each yoke, a collar is formed on the yoke. A pair of annular side covers each having a spherical inner surface slidable in contact with the spherical outer surface of the central cover each have an outer end portion horizontal in section and fixed to the periphery of the collar. An annular seal member in intimate contact with the outer surface of the central cover is provided at the inner end portion of each side cover. A clearance required for the sliding movement of the side covers is formed between the inner ends of the side covers. The connecting flange is so sized as to permit the side cover to pass thereover.
