To provide a lighting plate holding device and a lighting device capable of preventing deformation or damage of the lighting plate when the lighting plate is pushed up from below.SOLUTION: A lighting plate holding device 10 comprises a first set of rail parts 11 located above a ceiling 202 in a car and provided to house a first peripheral edge part 102B of a lighting plate 102 in a first direction A perpendicular to the vertical direction and a first set of clamping parts 12 located above the ceiling 202 and provided to clamp the first peripheral edge part 102B housed in the first set of the rail parts 11. Each of the first set of the rail parts 11 includes a first eaves part 11C which is located above each of the first set of the clamping parts 12 and protrudes further toward the inward of a lighting port 204 than each of the first set of the clamping parts 12. The stiffness of a first eaves part 11C is lower than the stiffness of the lighting plate 102.SELECTED DRAWING: Figure 3
【課題】照明板が下方から押し上げられたときに照明板の変形または破損を防止し得る照明板保持装置および照明装置を提供する。【解決手段】照明板保持装置10は、かご内において、天井202の上方に配置されており、かつ鉛直方向と直交する第1方向Aにおける照明板102の第1周縁部102Bを収容するように設けられている第1組のレール部11と、天井202の上方に配置されており、かつ第1組のレール部11に収容されている第1周縁部102Bを挟持する第1組の挟持部12とを備える。第1組のレール部11の各々は、第1組の挟持部12の各々よりも上方に配置されておりかつ第1組の挟持部12の各々よりも照明口204の内側に向かって突出している第1庇部11Cを含む。第1庇部11Cの剛性は、照明板102の剛性よりも低い。【選択図】図3
