Zusammenfassung: | PROBLEM TO BE SOLVED: To suspend an article such as a nameplate, without substantially damaging the door side, while surely preventing removal of a door scope by a malicious intent from the outdoor side of a door, in the door scope. SOLUTION: The door scope has a first cylinder body 2 inserted from the outdoor side of a door scope installing hole 6, a second cylinder body 3 inserted from the indoor side, and an out-fitting ring 4 rotatably held around its flange part to the outdoor side flange part 10 arranged in the first cylinder body 2. A spacer step part 21 forming an article locking clearance 20 between the out-fitting ring 4 and an outdoor side surface of the door 5, is arranged in the outdoor side flange part 10 of the first cylinder body 2.
