Abstract:
A lens drive apparatus includes a plurality of protrusions that protrude from an end of a magnet holder in a direction of an optical axis toward an inner wall surface of a cover and function as a fracture prevention supporting member. The plurality of protrusions are configured to support prevention of fracture in a plurality of suspension wires by contacting the inner wall surface of the cover when a magnet holder moves in the direction of the optical axis.
