ABSTRACT:
An objective lens drive apparatus includes a stationary member, a movable portion having an objective lens, an objective-lens holding member, and driving coils, and a plurality of rod-like elastic support members each having an axial direction parallel to a third direction perpendicular to a first direction and a second direction, the support members elastically supporting the movable portion so that the movable portion is movable to the stationary member in the first direction and the second direction. The movable portion is supported by the support members on both sides of the movable portion in the third direction, the support members are arranged on different planes perpendicular to the first direction, and the movable portion is arranged to be movable in the third direction with the support members, so that the objective lens is rotatable around an axis of the second direction.
