Zusammenfassung:PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture capable of suppressing rattling sound caused by vibration, even with a constitution in which a long light guide member is accommodated in an accommodation member.SOLUTION: A vehicular lighting fixture 10 includes: a long light guide member 12; a light source 13 provided opposing to an incident end surface 31 of the light guide member 12; and a long accommodation member 11 along a longitudinal direction Dl of the light guide member 12 so as to accommodate the light guide member 12 and the light source 13. At the light guide member 12, positioning protrusions 35 are provided which protrude, as a pair, in an orthogonal direction (Dw) orthogonal to the longitudinal direction Dl, across the whole length viewed in the longitudinal direction Dl. At the accommodation member 11, support protrusions 27 are provided on which the pair of positioning protrusions 35 are placed in a state of accommodating the light guide member 12, across the whole length viewed in the longitudinal direction Dl, as a pair in the orthogonal direction.SELECTED DRAWING: Figure 4 【課題】長尺な導光部材を収容部材に収容する構成であっても、振動に起因するガタツキ音を抑制することのできる乗物用灯具を提供する。【解決手段】長尺な導光部材12と、導光部材12の入射端面31に対向して設けられる光源13と、導光部材12および光源13を収容すべく導光部材12の長尺方向Dlに沿って長尺な収容部材11と、を備える乗物用灯具10である。導光部材12には、長尺方向Dlで見た全長に渡り、長尺方向Dlに直交する直交方向(Dw)へと対を為して突出する位置決め突起35を設け、収容部材11には、導光部材12を収容した状態において一対の位置決め突起35を載せる支持突起27を、直交方向で対を為して長尺方向Dlで見た全長に渡り設けている。【選択図】図4
