Claims

[Claims for Utility Model Registration] A plurality of parallel rail members for configuring an appliance mounting space provided together with a ceiling panel on the ceiling side, and a rail member placed on a rail portion constituting an opening edge of the appliance mounting space. a chassis body having a frame shape corresponding to the instrument mounting space; an opening provided in a vertical wall on the peripheral side of the chassis body; and a chassis body that is fixed to the chassis body by being inserted into the opening. At least a pair of insertion pieces formed in a substantially inverted V-shape are provided on the upper part of the main body, and are capable of engaging and detaching from the opening edge of the opening, and the main body faces a side surface of the rail member when the insertion pieces are inserted. a chassis regulating body provided with an upwardly directed hook portion at a lower portion of the rail member; and a convex portion provided on a side surface of the rail member for receiving the tip of the hook portion and regulating upward movement of the chassis body. A ceiling-embedded lighting fixture featuring:
