Abstract:
In an actuator (camera driver) according to the present invention, when a movable unit is in a neutral position in which the movable unit has rotated around neither an axis nor an axis, a first synthetic vector and a second synthetic vector are directed toward an object to be driven with respect to a plane including the both axes. The first synthetic vector is defined by synthesizing together two first vectors, pointing toward a pair of magnetic yokes, of magnetic attraction forces between a pair of first driving magnets and the pair of magnetic yokes. The second synthetic vector is defined by synthesizing together two second vectors, pointing toward a pair of magnetic yokes, of magnetic attraction forces between a pair of second driving magnets and the pair of magnetic yokes.
