Abstract: The disclosure provides an optical unit including a movable body including an optical module, a fixed body, and correction mechanisms for correcting the optical axis direction by changing the arrangement of the movable body with respect to the fixed body. An optical unit includes a movable body including an optical module, a fixed body surrounding the movable body in peripheral directions intersecting the optical axis direction of the optical module, and correction mechanisms that correct the arrangement of the movable body with respect to the fixed body. The correction mechanisms include a tilt mechanism that swingably supports the movable body with respect to the fixed body in directions intersecting the optical axis direction as rotation axes, and shift mechanism that movably supports the movable body with respect to the fixed body with the directions intersecting the optical axis direction.

Abstract: An optical unit with shake correction function capable of reducing a weight of a rotation member to be rotated in rolling correction. An optical unit with shake correction function includes: a movable member; a swing supporting mechanism supporting the movable member such that the movable member is able to swing; and a fixation member supporting the movable member via the swing supporting mechanism. The movable member includes: an imaging module; a rotation seat supporting the imaging module; a rotation supporting mechanism supporting the rotation seat such that the rotation seat is able to rotate on an optical axis of the imaging module; a supporting member supporting the rotation seat via the rotation supporting mechanism; and a rolling magnetic driving mechanism causing the rotation seat to rotate. The imaging module and the rotation seat configure the rotation member to be rotated by the rolling magnetic driving mechanism.

Abstract: An optical unit includes a subject-side rotary bearing part located on a subject side of an optical module and an image-side rotary bearing part located on an image side of the optical module. The two rotary bearing parts disposed on both the subject side and the image side of the optical module make it possible to restrain the tilt of the optical module and restrain backlash during a rotation of the optical module around an optical axis. This prevents the optical module from becoming a cantilever state and a twisting load from being applied due to an impact. Thus, it is possible to reduce the possibility of breakage of the rotary bearing parts due to an impact. A movable body includes a rotary bearing holder which swingably supports the optical module. A rolling magnetic-drive mechanism is disposed between the rotary bearing holder and a fixed body.

Abstract: An optical unit with a shake correction function may include a movable body which may include an optical module and a holder for holding the optical module, and a gimbal mechanism which swingably supports the movable body with respect to a fixed body. The gimbal mechanism may include a movable frame which is a gimbal spring. The movable frame may include a supporting point part and a connecting part including a meandering part. The meandering part has a cross-sectional shape in which on the assumption that a direction perpendicular to first and second axial lines is a first direction and a direction perpendicular to the first direction and a meandering path of the meandering part is a second direction, a thickness in the second direction is larger than a thickness in the first direction of each plate-shaped spring which structures the movable frame.
