Claims

[Scope of Claim for Utility Model Registration] (1) The heads of decorative screws screwed into two locations in the diametrical direction on the bottom of the ring-shaped simple mounting bracket attached to the ceiling correspond to the decorative screws on the main body of the device. Insert the large-diameter holes of a pair of mounting holes, each of which has a large-diameter hole at one end that has a roughly circular arc shape formed in two places, into which the head of the cosmetic screw can fit, and insert this cosmetic screw into the large-diameter hole opposite to the large-diameter hole of the mounting hole. In a device in which the main body of the device is attached to the ceiling by moving it relatively to the side and tightening it, the simple mounting bracket has concentric arc-shaped elongated holes at at least two locations in the diametrical direction, and the attachment device inserted into the elongated holes A lighting fixture characterized in that a simple mounting bracket is attached to the ceiling using screws, and the decorative screws are rotatable within a predetermined range hitting both ends of a slotted hole. (2) When the simple mounting bracket is attached to the ceiling with the mounting screws and rotated in one direction, the inner walls of the pair of elongated holes of the simple mounting bracket are frictionally engaged with the mounting screws, and the mounting bracket is fixed to the mounting screws. 2. The lighting fixture according to claim 1, characterized in that the lighting fixture is made of: (3) A ring-shaped simple mounting bracket attached to the ceiling is attached to the heads of cosmetic screws screwed into two locations in the diametrical direction of the bottom surface, and screws are screwed onto the heads of cosmetic screws screwed into two locations in the diametrical direction of the bottom surface of the device. Insert the large-diameter hole of a pair of mounting holes that are arc-shaped and have a large-diameter hole at one end into which the head of the cosmetic screw can fit, and then tighten the cosmetic screw by moving it relatively to the side opposite to the large-diameter hole of the mounting hole. In the case where the main body of the device is to be mounted on the ceiling, a substantially disc-shaped stopper having a stepped portion on the outer periphery that fits into the inner circumferential portion of the simple mounting bracket from below, and the simple mounting bracket is fitted into the stepped portion. A lighting fixture characterized by having a simple mounting bracket attached to the ceiling by screwing it to the ceiling while being rotatably held.
