[Problems to be Solved by the Invention] Incidentally, the ceiling surface of a wooden house is not always provided with construction members for fixing the appliance body frame 2 with wood screws. In addition, in wooden houses, the work of hanging lighting equipment using chains from hanging hooks attached to the ceiling is inefficient, as the lighting equipment must be hung parallel to the ceiling while adjusting the length of the chain. Also, if the ceiling is low, the light will be brought closer to the line of sight by the length of the chain, causing psychological discomfort as the light can be seen directly. Hanging the fixtures has a negative effect on the effect of the room, and since multiple stabilizers 4, etc. are scattered on the fixture frame 2 of the lighting fixture, it is difficult to hang the fixtures while maintaining balance. Minor adjustments are required to hang it.

[0006] Therefore, the present invention utilizes a hook sealing method when the mounting surface is made of wood, such as a wooden house or a reinforced concrete structure where the mounting surface is made of wood. An object of the present invention is to provide a lighting fixture mounting device that can reliably mount a lighting fixture in a stable state.
