To provide an interior lighting device capable of adjusting an optical axis direction of a light source by a smaller number of movable parts and being made compact by reducing dimensions of a rear side of a light source retaining body.
The light source retaining body 7 for supporting the light source 5 is rotatably supported on a guide surface 3b of a bezel 3 by abutment of mutual spherical surfaces and an irradiation direction of the light can be adjusted by turning of the light source retaining body 7, thereby, the optical axis direction of the light source 5 can be adjusted by the less number of movable parts. Further, by interposing a spherical surface-like light source side connection terminal 9 and a power source side connection terminal 11 slidably and elastically contacted with the light source side connection terminal 9 on a feed line to the light source 5, a feeder wire is not swung at turning of the light source retaining body 7 and dimensions of the rear side of the light source retaining body 7 are reduced to make it compact.
