A lamp body 20 includes a lamp unit 60 whose irradiation direction is changed according to a running state of a vehicle, a horizontal driving mechanism 90 for horizontally changing the irradiation direction, and a vertical driving mechanism 100 for vertically changing the irradiation direction. The horizontal driving mechanism and the vertical driving mechanism are integrated with each other, so that a lighting apparatus 10 can be mounted in a vehicle by using only a small mounting space. Moreover, the lighting apparatus 10 needs only small numbers of components and mounting man-hours.
