A vacuum servo apparatus capable of regulating the output accompanying the activation of an actuator to the maximum output or less includes a housing, movable walls located within the housing, a power piston, an input member, a valve mechanism, an output rod, a reaction disc and an actuator. A rear member forming part of an input member is able to move forward by a predetermined stroke with respect to a front member forming part of the input member so that the input member can be moved backward by the reaction disc in accordance with the activation of the actuator to cut off communication between rear chambers and the atmosphere.
