PROBLEM TO BE SOLVED: To aim at improvement in anti-glaringness effect. SOLUTION: A shade 8 is provided with shielding parts 82, 83 for shielding such light as becoming glaring light by reflecting on the lower part of a reflective surface 33 after passing the vicinity of the focus F of the reflection surface 33 of a movable reflector 3 by reflecting on the upper part of a glass tube sphere 43, out of the light from the sub-filament 40 of the light source bulb 4 of H4 type. As the result, the abovementioned glare light can be shielded by the shielding parts 82, 83 of the shade 8, anti-glaringness effect during lighting of a sub-filament (at the time of passing each other beam illumination) is improved. |
