Disclosed is a mirror actuator for adjusting an inclination angle of a side mirror or a rear mirror of a vehicle. The disclosed mirror actuator comprises a first rotary force supply unit, which rotates a rotary shell around a first rotary shaft; and a second rotary force supply unit, which rotates the rotary shell around a second rotary shaft. The first and second rotary force supply units respectively include a motor having a worm gear at the rotary shaft; a motor shaft engaged gear unit, which is engaged in the worm gear; a first double gear having a second double gear engaged gear unit coaxially rotating with the motor shaft engaged gear unit; a first double gear engaged gear unit, which is engaged in the second double gear engaged gear unit; a second double gear having a worm gear unit coaxially rotating with the first double gear engaged gear unit; a worm gear engaged gear unit, which is engaged in the worm gear unit of the double gear; a clutch gear having a rack gear engaged gear unit coaxially rotating with the worm gear engaged gear unit; a rack gear, which is engaged in the rack gear engaged gear unit and which the upper part protrudes out of the housing of the mirror actuator; and a coupling protrusion formed at the upper part of the rack gear and inserted into the rotary shell. |
