PROBLEM TO BE SOLVED: To shield harmful light without increasing the number of parts in a single lens reflex camera which prevents the light led from an eyepiece into a finder from adversely affecting an exposure result. SOLUTION: First light shielding walls 3a for shielding the light led from a finder screen 4 toward a mirror member 2 are formed in both ends in the direction of a turning shaft of a mirror support member 3 so as to rise toward the finder screen, and second light shielding walls 5a for shielding light led from the finder screen 4 toward the mirror member 2 are formed in both ends in the direction of a turning shaft 10 of a screen support member 5 so as to rise toward the mirror member 2. When the mirror member 2 is placed in a photographing position (a position receding from a photographic optical path), pairs of first light shielding walls 3a and light shielding walls 5a overlap each other respectively in a direction orthogonal to an optical axis L2 of a luminous flux for the finder.
