PROBLEM TO BE SOLVED: To facilitate positioning and provide a simple and inexpensive structure. SOLUTION: A guide projection 101 is provided on a side face of a room lamp 1 and an inclined side face 23 is provided in a recess 22 in a ceiling trim 2. When the room lamp 1 is contained in the recess 22 and temporarily fixed to the ceiling trim 2 by a temporary fixing means 4 and then securely fixed to a ceiling skeleton 3 by a fixing means 5, the guide projection 101 abuts on the inclined side face 23, so that the room lamp 1 and the ceiling trim 2 temporarily fixed to each other are positioned. At the same time, the room lamp 1 and the ceiling trim 2 temporarily fixed to each other are fixed to the ceiling skeleton 3. In this way, positioning is easily achieved. The positioning structure is simple and inexpensive because it consists of the guide projection 101 and the inclined side face 23. |
