A crank drive for the control of the sliding movement and of the tilting movement of the cover of sliding-lifting roofs of motor vehicles. A crank is provided that is rotatably disposed on a support to be mounted in a stationary manner, with said support having an internal toothing that is concentric with respect to the rotating axis of the crank, a toothed ring having an external toothing being in mating engagement with said internal toothing. The toothed ring is disposed on an eccentric firmly connected with the crank, with respect to rotation, so that it can be rotated around an axis which, with respect to the rotating axis of the crank, is radially displaced by an amount that is about equal to the difference of the tooth-root circle radii. A first stop arrangement for limiting the rotating movement of the crank in crank positions corresponding to the fully pushed-back and the fully tilted-out position of the cover is firmly connected with respect to rotation with the toothed ring, while a second stop arrangement for the releasable locking of the crank in the crank position that corresponds to the closed position of the cover is firmly connected with respect to rotation with the support. A crank chamber part concentrically encloses the support, which serves as the bearing body, and houses the toothed ring and the eccentric as well as the stop arrangements.
