Abstract:
1. A lens holder driving device comprising: an auto-focusing lens holder driving portion moving a lens holder holding a lens barrel along an optical axis; and an image stabilizer portion stabilizing image blur by moving said auto-focusing lens holder 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 fixed portion disposed apart from said auto-focusing lens holder driving portion in the direction of the optical axis; a plurality of suspension wires having first end portions fixed to said fixed portion 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 holder driving portion, said plurality of suspension wires swingably supporting said auto-focusing lens holder 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 holder driving portion comprises: a focusing coil fixed to said lens holder; a permanent magnet comprising four permanent magnet pieces which have first surfaces opposed to said focusing coil and which are disposed outsides of said focusing coil with respect to the optical axis in a radial direction so as to oppose to each other in the first direction and the second direction; a magnet holder, disposed around the periphery of said lens holder, holding said permanent magnet, said magnet holder having first and second ends opposite to each other in a direction of the optical axis; and first and second leaf springs, mounted to the first and the second ends of said magnet holder, supporting said lens holder in the direction of the optical axis shiftably so as to position said lens holder in the radial direction, wherein said fixed portion is disposed at a position in the vicinity of said second leaf spring, wherein the second end portions of said plurality of suspension wires are fixed to said first leaf spring at a wire fixing portion thereof; wherein said wire fixing portion serves as said fracture preventing member.
