Claims

[Scope of Claim for Utility Model Registration] 1. A winding device for winding wire on the main body of a lifting device installed in the ceiling, and a lifting body that is raised and lowered by a wire under the main body of the lifting device, and The cover that covers the opening in the ceiling is suspended via a rotating shaft of a hanging bracket that can swing freely in the direction of the inclination of the ceiling, and lighting fixtures, etc. are attached to the cover. A lifting device for a lighting fixture or the like, wherein the cover is provided with means for providing frictional resistance against swinging by a rotational support shaft. 2. The elevating device for lighting equipment, etc. according to claim 1, wherein the means for imparting frictional resistance is realized by tightly fitting the rotating support shaft with the elasticity of a leaf spring. 3. The elevating device for lighting equipment, etc. according to claim 1, wherein the means for providing frictional resistance is realized by a disc spring provided on the rotating shaft. 4. The device according to claim 1, wherein the means for providing frictional resistance is achieved by engaging coil springs, both ends of which are fixed to cover portions on both sides of the rotational support shaft, with contact surfaces provided between the rotational support shaft and the hanging fitting. Lifting device for lighting equipment, etc. 5. The elevating device for lighting equipment, etc. according to claim 1, wherein the means for providing frictional resistance is realized by the elastic force of a plate spring that swings relatively around a rotational support shaft.
