Abstract
A lens holding mechanism is used that has a lens; a lens barrel for securing the lens; a polarizing plate; a flat plate that is secured to the polarizing plate, and that has a protruding portion that protrudes, in respect to the polarizing plate, in a direction that is perpendicular to the optical axial direction; and a polarizing plate holder that is secured in respect to the lens barrel, and that contacts the protruding portion to secure the position of the flat plate. This structure is a structure for reducing stress that acts on a polarizing plate, providing a lens holding mechanism that suppresses the occurrence of screen due to stress.
