PURPOSE: A vehicle head lamp lens is provided to reduce the volume of the lens by dispersing refractive power to first and fourth surfaces. CONSTITUTION: A first side(300) and a second side(310) are convexly formed toward the side of emitting light. The first side and the second side emit light from a light source in parallel. A third side(400) and a fourth side(410) are formed smaller than the distance between the first side and the second side. The third side and the fourth side meet at least one of the first side and the second side. A central part uses a respective curved surface of the third side and the fourth side. |
