Abstract: PURPOSE: An actuator having a centrifugal brake is provided to limit the speed of an electric motor below the value, which pseudo vibration and noise generate, by directly installing the centrifugal brake to a rotor and to reduce a room for the actuator. CONSTITUTION: In an operating mechanism for operating an actuating member having an electric motor, a resetting spring(3), and a centrifugal brake(20), the actuating member is worked by the electric motor, which is activated by a control/regulating device, in a first movement direction and is operated in a second movement direction by the resetting spring. Accordingly, a brake body(22) of the centrifugal brake is arranged on a rotor(12) of the electric motor. The centrifugal brake directly arranged on the rotor generates a braking effect only when the actuating member is worked by the resetting spring. When the actuating member is worked by the switched-on electric motor, the centrifugal brake has no braking effect.
