Abstract
An imaging device comprises a first lens unit and a second lens unit. A first fixed barrel of the first lens unit movably holds a first lens frame, which holds a first lens group, in an optical-axis direction. A second fixed barrel of the second lens unit movably holds a second lens frame, which holds a second lens group, in the optical-axis direction. The first and second fixed barrels are secured in series in the optical-axis direction. The first and second lens units are adapted to be easily assembled in series in the optical-axis direction. Misalignment of the plural lens groups is prevented, and the first and second lens groups are accurately and individually moved in the optical-axis direction.
