ABSTRACT An object lens driving device causes partial rotation of movable members holding an object lens on an X-Y frame perpendicular to the optical axis of the object lens about a resilient hinge member as a fulcrum. The movable members are supported by base members. The hinge member interconnects the movable members and the base members. Electro-magnetic coils and magnets effectuate relative rotation of the movable members with respect to the base members about the hinge member. A rotational axis passing through the hinge member also passes through the position of center of gravity of the movable members and the balanced position of moment of inertia of the movable members.
