To miniaturize a vehicular lighting fixture unit.SOLUTION: A vehicular lighting fixture unit includes: a light source unit 11 in which a light source 24 is mounted and a heat sink 25 is provided; a light amount control mechanism 26 having a movable shade 29 for switching a shielding amount of light emitted from the light source and a solenoid 31 for operating the movable shade; and a projection lens 9 for projecting the light emitted from the light source frontward. A rotary shaft 39 of the movable shade and an output shaft 32 of the solenoid are arranged so as to extend in the left and right direction respectively, and the rotary shaft of the movable shade and the output shaft of the solenoid are arranged between the projection lens and a focal point S of the projection lens. Thereby, the vehicular lighting fixture unit can be miniaturized.SELECTED DRAWING: Figure 1 【課題】車輌用灯具ユニットの小型化を図る。【解決手段】光源２４が搭載されヒートシンク２５が設けられた光源ユニット１１と、光源から出射された光の遮蔽量を切り替える可動シェード２９と可動シェードを動作させるソレノイド３１とを有する光量制御機構２６と、光源から出射された光を前方へ投影する投影レンズ９とを備え、可動シェードの回動軸３９及びソレノイドの出力軸３２はそれぞれ左右方向に延在するように配置され、投影レンズと投影レンズの焦点Ｓとの間に可動シェードの回動軸とソレノイドの出力軸が配置された。これにより、車輌用灯具ユニットを小型化することができる。【選択図】図１
