Abstract
On the surface of Fresnel lens part which is formed on the back face of the lens in a door mirror, grain is provided. This grain includes the first grain formed in the first area positioned in the outside of the boundary extending in the front and rear direction of a vehicle, and the second grain formed in the second area positioned in the door panel side of the boundary, and the concavity depth of the second grain is deeper than that of the first grain. Consequently, illumination intensity of the light irradiated toward the face of the door panel from the deeper grain side of the second area can be reduced compared with the illumination intensity of the light toward the footstep from the shallower grain side of the first area. Adoption of such lens makes possible to apply in the various vehicle models through changing only the boundary position and concavity depth of the grain on the face of the Fresnel lens part.
