カメラのミラーの角度調整装置。 A mirror for a single-lens reflex camera that has a main mirror that swings between a first position where the screen situation is observed using a viewfinder and a second position that is retracted during shooting, and a sub-mirror that is swingably provided with respect to the main mirror. In the angle adjustment device, the main mirror is supported by a hinge provided on a rotatable member, and the rotation direction of the hinge is substantially parallel to the plane at the normal angular position of the sub-mirror at the first position, The sub-mirror is swingably supported by a hinge provided on the main mirror frame, and the main mirror is provided so as to be movable in parallel while securing a regular angle by an adjustment means, and the direction of the parallel movement of the main mirror is set by the direction of the parallel movement of the sub-mirror. 1. A mirror angle adjustment device for a single-lens reflex camera, characterized in that the mirror angle adjustment device is configured to be substantially parallel to a plane at a normal angular position.
