Claims

[Scope of utility model registration request]

A protective structure for a coupling screw body that removably fixes an annular globe holding frame to an opening at one end of a lamp body, wherein a substantially U-shape is formed on the outer periphery of the opening of the lamp body at a predetermined interval in the circumferential direction. One tightening member with a shaped cross section is attached to extend radially outward, and the other tightening member with a substantially inverted U-shaped cross section is attached to each of the positions of the annular glove holding frame corresponding to the one tightening member. A nut in which the member is attached so as to extend in a radial outward direction, and a coupling screw body that is penetrated from the other fastening member side to the one fastening member side is fixed to the horizontal wall portion of one fastening member. in the space formed by the covering plate that straddles the nut and is fitted and fixed between the vertical walls on both sides of one of the clamping members, and the horizontal wall portion and the vertical walls on both sides of one clamping member. A protective structure for a coupling screw body for a lighting device, characterized in that the nut and the tip of the coupling screw body protruding from the nut are positioned.
