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.
