Abstract:
1. A seat driving apparatus comprising: a gear transmission mechanism preventing a backlash by holding a gear engagement by means of a wedge member applied with a biasing force of a biasing member and transmitting a torque by displacing the wedge member; an actuator operating a seatback of a seat via the gear transmission mechanism; and a control unit controlling driving of the actuator, wherein the control unit includes a seat operation mode in which the actuator is driven to operate the seatback at a predetermined speed and a creep mode in which the actuator is driven at a slower speed than the predetermined speed in the seat operation mode, and wherein the actuator is driven in the creep mode until a load for releasing the holding of the gear transmission mechanism is applied to the wedge member and subsequently the actuator is driven in the seat operation mode when the seatback is operated in an opposite direction from the previous operational direction thereof.
