To provide a vehicle interior lighting device capable of detecting a change of a capacitance stably, in switching between turning on and off.SOLUTION: A vehicle interior lighting device 1 comprises: a housing 12 comprising, an annular lens contact surface 12d which surface-contacts along an outer peripheral shape of a light reception surface 13d of a light transmission part 13a, and a bus bar contact surface 12i; a first bas bar 14 which has an electric conductive annular electrode part 14a; a first holder 15 which has an annular contact end 15j being formed in a shape along a shape of the electrode part 14a, and holds the first bas bar 14 by bringing the contact end 15j into contact with the electrode part 14a; and a control part 22 for switching on/off of a light source 20 according to a change of a capacity between the electrode part 14a and a part of a human body touching a light radiation surface 13c. The electrode part 14a is a flat plate body where a first main flat surface 14c surface-contacts the bas bar contact surface 12i, and a second main flat surface 14d faces the contact end 15j. The electrode part 14a has a first energization part 14e for applying energization force to the contact end 15j.SELECTED DRAWING: Figure 6
【課題】点灯と消灯との切り替えに際して安定的に静電容量の変化を検知する車室内照明装置を提供する。【解決手段】車室内照明装置1は、光透過部13aの受光面13dの外周形状に沿って面接触する環状のレンズ接触面12dと、バスバー接触面12iとを有するハウジング12と、環状の電極部14aを有する導電性の第1バスバー14と、電極部14aの形状に沿った環状の接触端部15jを有し、接触端部15jを電極部14aに接触させることで第1バスバー14を保持する第1ホルダー15と、光照射面13cを触れた人体の一部と電極部14aとの間の静電容量の変化に応じて光源20のオン/オフを切り替える制御部22とを備える。電極部14aは、第1主平面14cがバスバー接触面12iと面接触し、第2主平面14dが接触端部15jと対向する平板体である。電極部14aは、接触端部15jに対して付勢力を与える第1付勢部14eを有する。【選択図】図6
