Abstract:
A movable device includes a movable part including a mirror unit; a torsion bar with one end coupled to the movable part; a first cantilever part coupled to the other end of the torsion bar; a second cantilever part with one end coupled to a coupling portion of the first cantilever part; a stationary part coupled to the other end of the second cantilever part; and a driver configured to deform the second cantilever part. A width of the coupling portion of the first cantilever part, to which the second cantilever part is coupled, is narrower than a width of the second cantilever part in a width direction of the coupling portion.
