The invention provides an electric actuator of a hidden door handle mechanism for a vehicle. The electric actuator of the hidden door handle mechanism for the vehicle comprises an output gear, a bearing, a shaft seal, a speed reducer, a direct-current motor and elastic sealing sleeves; the output gear is fixed on an output shaft of the speed reducer; a cylindrical bearing, the shaft seal and a cylindrical bearing are sequentially arranged in an inner hole of a shell at the end of the output shaft of the speed reducer; the direct-current motor is connected with the speed reducer through a motoroutput shaft; the elastic sealing sleeves sleeve on the outer shells of the direct-current motor and the speed reducer; a wire harness positioning sleeve is further arranged on the outer circle of each elastic sealing sleeve to fix a wire harness; and the wire harnesses penetrate through the elastic sealing sleeves to be connected and be in conduction with the direct-current motor. The electric actuator is good in sealing and waterproof effect, easy to assemble, high in production efficiency, low in cost and convenient to disassemble and maintain.
