Abstract

The lens drive device provided according to the present disclosure includes a lens having an optical axis, a lens holder supporting the lens, an image stabilization frame, a base, and a drive component. The lens holder is elastically supported inside the image stabilization frame by a first elastic sheet, and the image stabilization frame is elastically supported on the base in the direction along the optical axis by a suspension component, where the suspension component includes a second elastic sheet and a suspension wire. The second elastic sheet includes a fixing portion and a suspension portion, and the suspension portion can be elastically deformed in the direction along the optical axis to buffer impact acted on the suspension wire. The lens drive device provided according to the present disclosure buffers the impact acted on the suspension wire by the suspension portion, so that the structural stability is provided.
