VEHICLE DOOR ACTUATOR, IN WHICH THE RESISTANCE INCREASE OF A PTC ELEMENT IS PREVENTED

摘要

PURPOSE: A vehicle door actuator is provided to prevent increase of resistance of a PTC element by forming projecting parts on both sides of a rotary shaft. CONSTITUTION: A vehicle door actuator includes a motor and a gear in order to perform a locking function and an unlocking function. The motor is installed at an upper part of a commutator. The gear is in contact with a screw part(31a) of a rotary shaft(31) of the motor. A projecting part(35) is formed at a screw part of the rotary shaft of the motor. Oil flowing to the rectifier is prevented by the projection part. The projecting part is projected from both sides of the rotary shaft.
