A pneumatic actuator consisting of an elongate, substantially cylindrical hollow body ( 1 ) impinged upon by a pressurized fluid. A pressure rod ( 2 ) which is resistant to bending and which can be stressed by axial forces is placed on the lower side thereof. The free end thereof is embodied as a node ( 3 ) to which two traction elements ( 4 ) are secured and the other end is embodied as a rotating joint ( 7 ) which rotationally connects the pressure rod ( 2 ) to a traction system ( 8 ). The axial ends of the hollow body ( 1 ) are respectively provided with a cap ( 5 ). The hollow body ( 1 ) is connected thereto along a casing line of the hollow body ( 1 ) in a non-positive fit. When the hollow body ( 1 ) is impinged upon by a pressurized fluid, the traction elements ( 4 ) are forced by the inflating hollow body ( 1 ) out of the straight connecting line between the fixing point ( 9 ) and the node ( 3 ) in the form of a screw and pull the node ( 3 ) into an activated position which is represented with dashed lines
