Title:
OPTICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/009402
Kind Code:
A1
Abstract:
An elastic support part in this optical device is provided with: a pair of levers which face each other in a second direction orthogonal to a first direction; a pair of first torsion support parts which extend in the second direction, and are respectively connected between the pair of levers and a base; a pair of second torsion support parts which extend in the second direction, and are respectively connected between the pair of levers and a movable part; and a first link member which bridges a gap between the pair of levers. The pair of levers and the first link member demarcate a light passage opening. Each of the positions where the pair of levers are connected with the pair of first torsion support parts is positioned at the opposite side to the movable part with respect to the centre of the light passage opening in a third direction orthogonal to the first direction and the second direction. The maximum width of the light passage opening in the second direction is defined by the interval between the pair of levers in the second direction.
