Light emitted from the light source, which is disposed above an optical axis extending in front and rear direction of a vehicle lighting device, is reflected toward front of the vehicle lighting device by a reflector made of a transmissive member. An exterior surface of the reflector is formed with a plurality of protruding portions extending in a radial pattern with respect to the optical axis. Each of the protruding portions has a total reflection prism having a cross sectional shape perpendicular to the optical axis, which is approximately a V shape. The reflector is divided into twelve fan-shaped reflective regions, each having three protruding portions. The fan-shaped reflective regions, which are located in the left and right directions of the optical axis, reflect the light emitted from the light source in the direction more deviating from a direction along the optical axis than the fan-shaped reflective regions, which are located at the upper and lower directions of the optical axis.
