ABSTRACT:
A mirror driving apparatus for a camera which rotatably drives a mirror between two predetermined position, by an elastic restoring force stored in a mirror biasing member, including an engaging device which retains an elastic restoring force in the mirror biasing member, and a disengaging and shock absorbing spring which elastically biases the engaging device in a disengaging direction thereof when the mirror is in one of the predetermined position. The disengaging and shock absorbing spring biases the mirror in a direction to stop the same immediately before the movement of the mirror is completed when the mirror is moved to the other of the predetermined position by the elastic restoring force of the mirror biasing member.
