1. A vehicle hinge driving apparatus, the apparatus comprising:
an actuator;
a housing connected to the actuator;
an output shaft rotatably mounted in the housing;
a transmission mechanism configured to transmit a torque from the actuator to the output shaft; and
a brake unit mounted on the transmission mechanism;
wherein the brake unit comprises a friction member frictionally contacting a transmission shaft of the transmission mechanism, a spring configured to apply an elastic force to push the friction member toward the transmission shaft, and an adjusting member configured to adjust the elastic force of the spring;
wherein the spring is interposed between the friction member and the adjusting member;
wherein the friction member includes a retainer recess and a retainer projection protruding upwardly from the retainer recess;
wherein the adjusting member includes a retainer recess provided in a bottom surface of the adjusting member;
wherein a top end of the spring is supported by the retainer recess of the adjusting member;
wherein a bottom end of the spring is supported by the retainer recess and the retainer projection of the friction member; and
wherein the housing comprises a cavity in which the friction member is received and two guide projections opposing each other in the cavity for guiding linear movement of the friction member relative to the cavity.
