PURPOSE:To achieve large driving force with small and light structure, by transmitting the motion of movable section due to air pressure through a power multiplier mechanism based on the principle of lever. CONSTITUTION:Upon air feed to an air feed hole 32, the air pressure in a pressure chamber comprised of a casing 31, seat valve 34, piston 33 and O-ring 13 will increase to slide the piston 33 against the pressure of spring in axial direction by the distance between a disc 37 and an armature 35. Here the movement of armature 35 is 81 to push a push rod 1 through a movable chip 36 thus to move by 82. The movable chip 36 will function as a power multiplier employing the principle of lever. When multiplying the moving force of the piston 33 and converting the direction of force by means of the movable chip 36, the size and the weight can be reduced when compared with conventional driver for producing same driving force.
