Since the erroneous assembly preventing projection 28 is formed which abuts against the upper insertion plate portion 12 to prevent the movement thereof to the wall surface H side, the lower horizontal plate portion 10 is at a level to enter the second insertion recess 24. However, when the upper insertion plate portion 12 is positioned below the front end portion 20 of the support arm 2 (the state of FIG. 10), the front surface of the misassembly preventing projection 28 causes the upper insertion plate portion 12 to be further wall-mounted. It is possible to prevent the lower lateral plate portion 10 from entering the second insertion recess 24 so that the cover body 1 cannot move to the H side, and the cover body 1 can always be properly attached from below. That is, in the illustrated example, the stroke in the horizontal direction between the front surface of the misassembly preventing protrusion 28 and the entrance 24g of the second insertion recess 24 is determined by the tip of the upper insertion plate 12 and the lower insertion plate 13. It is designed to be larger than the stroke in the horizontal direction with the tip.

In the illustrated example, the support arm 2
In the upper part of the front end portion 20 of the
Since a hooking protrusion 29 that protrudes upward is formed at a distance from 3a, the hooking portion 24 on the side of the support arm 2 for exchanging the light source K that constitutes the lighting fixture or the like.
Even if the cover body 1 is pulled away from the wall surface H by a force large enough to release the engagement between the a and the engaged portion 13a on the side of the cover body 1 and the engagement is released, the hooking protrusion The cover body 1 is provided on the side facing the wall surface H side of 29.
The tip of the upper insertion plate portion 12 can be hooked so that the disengaged cover body 1 does not unexpectedly drop. (Figure 9)

In the illustrated example, the forwardly facing step surface 25c formed on the front end portion 20 of the arm main body 25 constituting the support arm 2 is moved to the lowermost side of the arm main body 25 as it goes downward. It is an inclined surface that is inclined toward the front end, and the tip of the upper insertion plate portion 12 of the cover body 1 that is abutted against this step surface 25c (inclined surface) is first moved by this step surface 25c (inclined surface). The cover body 1 can be more easily attached to the pair of support arms 2 and 2 from below.
