LENS DRIVE DEVICE, AND CAMERA MODULE AND CELLULAR PHONE EQUIPPED WITH LENS DRIVE DEVICE

摘要

Disclosed is a lens drive device in which a holder moves accurately in the optical axis direction with smooth movement, even in cases which the distance between shaft-bottom support units and the distance between shaft-top support holes are incongruent. A vertical cross section in the optical axis direction of at least one shaft-top support hole (42) from among the aforementioned plurality of shaft-top support holes (41, 42) disposed on a cover is larger than the vertical cross section in the optical axis direction of a corresponding secondary shaft (52) from among a plurality of shafts (51, 52).
