ABSTRACT:
A shock absorber of a mirror in a single lens reflex camera having a mirror which rotates about a shaft to move between a viewing position and a retracted position includes a rotating member which rotates together with the mirror when the mirror rotates, a brake member which is rotatable about a shaft, a friction member which resists the rotation of the brake member, and an association member which is provided on the rotating member to rotate the brake member together with the rotating member in the same direction when the rotating member rotates in the forward or reverse direction, at the termination of the upward movement of the mirror from the viewing position to the retracted position or at the termination of the downward movement from the retracted position to the viewing position.
