Abstract
A tilt correction unit includes: an inner frame, inside which an optical unit is held; an outer frame surrounding the inner frame, with a gap formed between the inner frame and the outer frame around an entire perimeter of the inner frame; an elastic part which is disposed between the outer frame and the inner frame and elastically supports the inner frame inside the outer frame; a rotational movement support part that connects a part of an outer peripheral surface of the inner frame to a part of an inner peripheral surface of the outer frame; and a drive unit that comprises a magnet and a coil disposed opposite each other with a gap therebetween, wherein the inner frame is driven by the drive unit and rotates about the rotational support part, in a plane perpendicular to the optical axis of the optical unit.
