A driving device is provided that can suppress power consumption, and is excellent in response characteristics, and also capable of appropriately adjusting a revolving angle of a target member. According to an exemplary design, the device includes a rotational shaft supported by a housing and is capable of revolving in each of a positive and counter rotation direction about a Z-axis. Shape memory alloys formed in a wire-like shape apply an external force acting in the positive rotation direction to the rotational shaft by heat shrinkage. A bias spring applies an external force acting in the counter rotation direction to the rotational shaft. Moreover, a wiper is displaced following the rotation of the rotational shaft. A power supply system including power supply terminals, a relay member, relay terminals, and lead wires separately supplies power to three or more mutually different positions of the shape memory alloys.
