A cardan-type joint has flanges which are arranged on mutually facing shaft ends and preferably have three axially projecting driving pins, respectively, which are mutually staggered and uniformly arranged on the circumference of a common graduated circle. The driving pins are connected with one another in a torsion-proof manner by a flexible joint ring which is provided in corner points with sockets for the driving pins. The multi-part joint ring is formed by a collar of several oval driving loops. Each of the driving loops winds around two adjacent sockets. In order to easily permit relatively large bending angles during rotation, even in the event of a high mechanical and thermal loading of the cardan-type joint, the oval driving loops are indirectly or directly swivellably disposed on the driving pins by a pair of contact surfaces which are round in a meridian section in an axially slidable manner on the socket or on the driving loop. In this case, as viewed radially from the outside, the contact surface pairs may be made concave or convex. In the case of a convex contact surface shape, a spherical shape is preferred.
