Abstract
A lens driving device for a camera or the like drives a lens through a correct distance by the distance through which the lens is driven being corrected according to errors in mechanical parts; as a result it is not necessary for the mechanical parts to be made of high precision, and maintenance of molds used in their manufacture can therefore be made easy.
