PURPOSE:To increase the quantity of light to be led outside via respective lens members by making the inner surface of a lens roughly flush, joining a reinforcing member made of colorless transparent resin all over the outer surface of the lens, and thereby making the width of each shade narrow while sufficient joint strength is being secured. CONSTITUTION:The inner surface of a lens 6 is made roughly flush, and a joint reinforcing member 7 made of colorless transparent resin is bonded all over the outer surface of the lens 6. Sufficient joint strength can thereby be secured without holding each shade with ribs formed as they are in former ones because the joint reinforcing member 7 made of colorless transparent resin is bonded all over the outer surface of the lens 6. By this constitution, the width of each shade 5a and 5b can thereby be made narrow, the quantity of light to be led outside can therefore be increased. |
