Title:
DRIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/110746
Kind Code:
A1
Abstract:
The present invention provides a driving device that can be reduced in overall size. A mirror (2) is rotatably supported by a rotary frame (3) via inner torsion bars (20), and the rotary frame (3) is rotatably supported by a base part (4) via outer torsion bars (30). By providing magnetic elements (5A, 5B) on the rotary frame (3), the mirror (2) and ends (74, 75) of yoke parts (7A, 7B) are inhibited from interfering with each other, and, by disposing the magnetic elements (5A, 5B) and the ends (74, 75) close to each other, the size of the overall device can be reduced.
