Patent attributes
An optical unit that corrects a shake of an optical module includes: a movable portion having a holder that holds the optical module; and a fixed portion that rotatably supports the movable portion. The movable portion is rotatable relative to the fixed portion in first-third rotation directions correspondingly centered on first-third axes which correspondingly extend in first-third directions. The first direction is parallel to an optical axis direction of the optical module in a state in which the movable portion is stationary. The first direction, the second direction, and the third direction are perpendicular to each other. The movable portion further includes a protrusion protruding toward the fixed portion from an end of the holder closer to the fixed portion in the optical axis direction. The fixed portion includes a support portion that rotatably supports the protrusion.
