Claim Text:
1. A lens driving device comprising: an auto-focusing lens driving portion moving a lens holder holding a lens barrel along an optical axis; and an image stabilizer portion stabilizing blurred image by moving said auto-focusing lens driving portion in first and second directions which are orthogonal to the optical axis and which are perpendicular to each other, wherein said image stabilizer portion comprises: a base disposed apart from said auto-focusing lens driving portion in the direction of the optical axis; a plurality of suspension wires having first end portions fixed to said base at outer regions thereof, said plurality of suspension wires extending along the optical axis and having second end portions fixed to said auto-focusing lens driving portion, said plurality of suspension wires swingably supporting said auto-focusing lens driving portion in the first direction and the second direction; and a fracture preventing member preventing said plurality of suspension wires from fracturing, wherein said auto-focusing lens driving portion comprises; a lens holder comprising a tubular portion holding said lens barrel; a focusing coil fixed to said lens holder so as to position around said tubular portion thereof; a permanent magnet disposed opposite to said focusing coil; a magnet holder disposed around an periphery of said lens holder and holding said permanent magnet at an outside of said focusing coil; first and second leaf springs mounted to the first and second ends of said magnet holder, and supporting said lens holder shiftably in the direction of the optical axis so as to position said lens holder in a radial direction, said first leaf spring being disposed farther apart from said base than said second leaf spring; and a plurality of projecting portions, as a fracture prevention supporting member supporting prevention of fracture in said plurality of suspension wires, projecting in the direction of the optical axis from the first end of said magnet holder to which said first leaf spring is mounted, the second end portions of said plurality of suspension wires are fixed to said first leaf spring, and said first leaf spring comprises a wire fixing portion extending around each of said plurality of protecting portions and having parts to which the second end portions of said plurality of suspension wires are fixed, said wire fixing portion serving as said fracture preventing member.
