Abstract:
1. An in-vehicle illuminating device, comprising: one or more rod-shaped light guiding bodies each having an inner surface, a first end and a second end provided in a longitudinal direction, said one or more rod-shaped light guiding bodies reflecting, on the inner surface, light rays incident on an optical incidence plane provided at the first end thereof to guide the reflected light rays to the second end thereof, a luminous source arranged in the vicinity of said optical incidence plane, said luminous source emitting light in a direction orthogonal to the longitudinal direction of said one or more rod-shaped light guiding bodies, and a light introducing body arranged between said luminous source and said optical incidence plane, said light introducing body comprising a reflecting surface on the inner surface to introduce, via said reflecting surface, luminous flux emitted from said luminous source to said optical incidence plane, wherein said light introducing body includes a lamp hole for inserting said luminous source therethrough and a light guide hole for inserting the end of said rod-shaped light guiding body therethrough, said lamp hole being opened in a direction orthogonal to said light guide hole, and wherein an inner end of said light guide hole is connected with said inner surface of said light introducing body, and the end of said rod-shaped light guiding body inserted thereinto abuts against said inner surface of said light introducing body, to thereby permit said rod-shaped light guiding body to be held at a position in which said optical incidence plane is within a range of the luminous flux emitted from said luminous source.
