The invention relates to a clamping and/or braking device with a base element ( 7 ) and a force-applying element ( 17 ), by means of which the generated clamping and/or braking forces can be transferred to an object ( 39 ), as well as at least two adjacent wall sections ( 3 ), which each apply force with an end region on the base element ( 7 ) and the force-applying element ( 17 ), and wherein the two or more adjacent wall sections ( 3 ) define an essentially sealed pressure chamber that can be pressurized with pressure or negative pressure, wherein the two or more wall sections ( 3 ) each have a bending region ( 3 a), which is resistant to tensile force and nevertheless can be bent elastically so that the bending regions ( 3 a) form an elastic element between the base element ( 7 ) and the force-applying element ( 17 ). By means of the force-applying element ( 17 ), in the unpressurized built-in state of the clamping and/or braking device ( 1 ), a predetermined clamping and/or braking force can be exerted on the object ( 39 ), wherein the two or more wall sections ( 3 ) and their bending regions ( 3 a) are formed, such that when the pressure chamber is pressurized with positive pressure or negative pressure as a result of a change in the curvature of the bending regions ( 3 a), the clamping and/or braking forces transferred by the force-applying element ( 17 ) to the object ( 39 ) are changed or the force-applying element ( 17 ) is moved in the direction towards the base element ( 7 ) or away from this element. According to one alternative, the two more adjacent wall sections ( 3 ) can also be connected rigidly to the force-applying element ( 17 ) and/or to the base element ( 7 ).
