To provide an indoor lighting device for vehicle capable of presenting visual vastness even in a limited space of an indoor space of a vehicle and capable of suppressing the number of components.SOLUTION: An indoor lighting device for vehicle is constituted in indoors of a vehicle and includes: light emitting means for emitting light; and a light guide body 50 for guiding light of the light emitting means. The light guide body 50 is integrally constituted with: a partial reflection surface 51 for transmitting part of light and reflecting the rest on a surface disposed on the indoor side of the vehicle; a total reflection surface 52 for totally reflecting the light on the surface disposed at a position facing the partial reflection surface 51; and an incident angle change element 54 for changing the incident angle of the light in the light guide body 50.SELECTED DRAWING: Figure 4
【課題】乗物の室内空間の限られたスペースであっても視覚的な広がりを演出できると共に、部品点数を抑制し得る乗物用の室内照明装置を提供する。【解決手段】乗物用の室内に構成される乗物用の室内照明装置であって、光を発する発光手段と、発光手段の光を導光する導光体50と、を有し、導光体50は、乗物の室内側に配される面において光の一部を透過させ残りを反射させる一部反射面51と、一部反射面51と対向する位置に配される面において光を全反射させる全反射面52と、導光体50内における光の入射角を変更させる入射角変更要素54と、が一体に構成される。【選択図】図4
