PROBLEM TO BE SOLVED: To regulate the lateral direction, longitudinal direction, and vertical direction of an end plate by forming the cross section of the end plate into a Z-shape, providing notch sections at both ends of the end plate, and providing fixed pieces holding the front face of the end plate at the inner face rise sections of side channels having a nearly U-shaped cross section. SOLUTION: The upper section of an end plate 5 is folded to the reflector side into a Z-shape, and notch sections 5a are provided at both end sections of the end plate 5 in contact with the inside and lower side of side channels 4. Fixed pieces 10 for regulating the movement of the end plate 5 are inserted and fitted to the inside rise sections of the side channels 4 to be located in the front of the end plate 5. The lateral, longitudinal, and vertical movements of the end plate 5 can be regulated, the end plate 5 is not pushed up even when an accessory is fitted, the execution property can be improved, the packing work is made efficient, and the cost can be reduced. |
