PROBLEM TO BE SOLVED: To solve a problem that a mirror angle at a standby position is shifted from that in an early stage in a quick return mirror mechanism of a single lens reflex camera when operation speed becomes high and a number of repetitive using times becomes large. SOLUTION: By insert-molding a metallic member into a portion of a mirror holding member made of resin abutting on a regulation member, the shift of the mirror angle at the standby position from that in the early stage is reduced.
