The door vision displays the image information, which is taken by the external photographing device, through the internal displaying device. One end of the central axis, which is exposed toward the guide hole formed at the rear cover, is connected to the handle and inserted into the boss at the central inner side of the rear cover. A lever comprising a connecting axis is formed to be inclined at an angle to the opposite direction of the central axis. A supporting frame on which the substrate of the lower part of lens body is fixed to the front side has a boss fitted into the lever connecting axis. A clamp, which maintains the lens body and allows it to move freely, is placed fixedly toward the inside of the front cover having a sight glass.
