STRUCTURE FOR MOUNTING ILLUMINATION DEVICE ON VEHICULAR INTERIOR MEMBER

To provide a structure for mounting an illumination device on a vehicular interior member, allowing a long light guide to be mounted on the vehicular interior member while simply and stably setting the position of the end face of the long light guide at a prescribed position.SOLUTION: An illumination device 30 includes an LED 31 (light source) and a long light guide 33. A door trim 1 is plate-shaped and includes a plurality of open holes H for allowing light guided by the light guide 33 to pass from the rear face side of the door trim 1 to the front face side thereof. The light guide 33 has one end face arranged so as to be opposed to the LED 31 and is arranged so as to guide the light to the two or more open holes H and illumination windows. The door trim 1 includes a configuration (end fixing mechanism) for fixing another end of the light guide 33 while opposing another end face 33A of the light guide 33 to one of the open holes H and keeping a distance between the other end face 33A and the one of the open holes H.SELECTED DRAWING: Figure 2 【課題】長尺の導光体の端面の位置を所定の位置に簡便かつ安定に定めて乗物用内装材に取付けることが可能な乗物用内装材に対する照明装置の取付構造。【解決手段】照明装置３０は、ＬＥＤ３１（光源）と、長尺の導光体３３とを備え、ドアトリム１は、板状をなし、導光体３３によって導光された光をドアトリム１の裏面側から表面側に通すための貫通孔Ｈを複数備えており、導光体３３は、一方の端面がＬＥＤ３１に対向して配されるとともに、２つ以上の貫通孔Ｈおよび照明窓に導光するように配策されている。ドアトリム１は、導光体３３の他方の端面３３Ａを１つの貫通孔Ｈに対向させ、かつ、他方の端面３３Ａと１つの貫通孔Ｈとの距離を保持した状態で、導光体３３の他方の末端を固定する構成（末端固定機構）を備えている。【選択図】図２
