LENS HOLDER DRIVING DEVICE

摘要

A lens holder driving device includes 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 blurred by moving the 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. The image stabilizer portion includes: a fixed portion disposed apart from the auto-focusing lens holder driving portion in the direction of the optical axis; a plurality of suspension wires having first end portions fixed to the fixed portion at outer regions thereof, extending along the optical axis, having second end portions fixed to the auto-focusing lens holder driving portion, and swingably supporting the auto-focusing lens holder driving portion in the first direction and the second direction; and a fracture preventing member preventing the suspension wires from fracturing.
