Title: LENS HOLDING MECHANISM AND IMAGE CAPTURING DEVICE
Abstract:
Provided is a lens holding mechanism comprising: a lens; a lens barrel to which the lens is affixed; a polarizer plate; a flat surface plate affixed to the polarizer plate and having a protrusion protruding relative to the polarizer plate in the direction perpendicular to the optical axis direction; and a polarizer plate holder affixed to the lens barrel and in contact with the protrusion to affix the position of the flat surface plate. As a result of this configuration, in the provided lens holding mechanism, stress applied to the polarizer plate is reduced and strain caused by the stress is suppressed.
