Abstract:
A driving device capable of downsizing the entire device is provided. A mirror (2) is rotatably supported by a rotary frame (3) via an inner torsion bar (20), and the rotary frame (3) is rotatably supported by a base part (4) via an outer torsion bar (30). Magnetic elements (5A, 5B) are provided on the rotary frame (3), thus the mirror (2) and ends (74, 75) of yoke parts (7A, 7B) are prevented from interfering with each other, and, by disposing the magnetic elements (5A, 5B) and the ends (74, 75) close to each other, the entire device can be downsized.
