Document Type and Number:
WIPO Patent Application WO/2022/180736
Kind Code:
A1
Abstract:
An actuator (10) comprises a mirror (20), an inner frame (60), an outer frame (50), and a torsion bar (52). The mirror (20) has a reflection surface (22). The inner frame (60) supports the mirror (20). The outer frame (50) supports the inner frame (60). The torsion bar (52) connects the outer frame (50) and the inner frame (60). The inner frame (60) is swingable with a first axis (201) as a swing axis with respect to the outer frame (50). The mirror (20) is swingable with a second axis (202), which is nonparallel to the first axis (201), as a swing axis with respect to the inner frame (60). When the length of the torsion bar (52) is denoted by L, the thinnest portion (520) of the torsion bar (52) is L/5 or more away from joint portions at both ends.
