Abstract: The invention relates to a gripper mechanism for a manipulator or the like, having at least one movable gripper finger (6) swingable around a slide axis, as coupler of a kinematically multi-member positive guide mechanism (1, 2, 3, 4, 5, 6), which contains at least one slider/crank mechanism (1, 2, 3, 4) as actuating unit which has a crank (2) acting at one end on a first link (3) and pivoted at the other end on a slide rod (1), and a slide (4) which is guided on the slide rod (1) and abuts against the first link (3), a second link (5) being supported axially displaced therefrom on the slide (4) and both links (3, 5) of the guide mechanism acting on the gripper finger (6), the slide rod (1) carrying out no movement in the direction of the slide axis upon the movement of the gripper, and its strives for and achieves a flexurally as well as torsionally stiff development of such a gripper mechanism by a slide rod (1) which is formed of several decentrally arranged rods (7) as cage.
