To provide a vehicular lighting device and a vehicular lighting fixture capable of suppressing a positional deviation in a rotating direction.SOLUTION: A vehicular lighting device includes: a pair of mouthpieces; a substrate provided between the mouthpieces; at least one light emitting element provided on the substrate; and at least one rotation preventive portion extending in a direction which the pair of mouthpieces faces. The mouthpiece has a body portion, and a tip end portion provided on an end portion on the opposite side to the substrate side of the body portion. The tip end portion gradually decreases dimensions in a direction orthogonal to the direction which the pair of mouthpieces faces toward the tip end side. A distance between the end portion on the tip end portion side of the rotation preventive portion and the end portion on the substrate side of the body portion, is larger than a distance between the end portion on the opposite side to the substrate side of the body portion and the end portion on the substrate side of the body portion.SELECTED DRAWING: Figure 2

    【課題】回転方向の位置がズレるのを抑制することができる車両用照明装置、および車両用灯具を提供することである。【解決手段】実施形態に係る車両用照明装置は、一対の口金と;前記口金と、前記口金と、の間に設けられた基板と;前記基板の上に設けられた少なくとも1つの発光素子と;前記一対の口金が対峙する方向に沿って延びる少なくとも1つの回り止め部と;を具備している。前記口金は、本体部と、前記本体部の、前記基板側とは反対側の端部に設けられた先端部と、を有している。前記先端部は、先端側になるに従い、前記一対の口金が対峙する方向と直交する方向の寸法が漸減している。前記回り止め部の前記先端部側の端部と、前記本体部の前記基板側の端部と、の間の距離は、前記本体部の前記基板側とは反対側の端部と、前記本体部の前記基板側の端部と、の間の距離よりも大きい。【選択図】図2
