PURPOSE:To contrive miniaturization of an actuator itself by using a small drive motor so as to be applicable, in the case of the brake actuator operated by driving the motor to perform step-in control of a brake pedal. CONSTITUTION:A transmitting mechanism 13, having a pair of non-linear gears 13a, 13b, is interposed between rotary shafts 17a, 17b, for transmitting drive force of a drive motor 11 to an operating arm 14, to generated non-linear action based on speed change ratio of this transmitting mechanism 13 in an output side thereof. Accordingly, an output of the drive motor 11 is required in only a value smaller than a value of maximum operating speed F0 X maximum operating force B0, and miniaturization of an actuator itself can be contrived with application possible of the small drive motor. |
