<P>PROBLEM TO BE SOLVED: To improve light distribution characteristics in a two-bulb head lamp of a projector type. <P>SOLUTION: A looseness of a traveling direction of a plunger 14 is regulated by an elastic engagement with an engaging part 24 and a mounting thin plate part 25 and by a taper engaging with a taper part 40 and the mounting thin plate part 25. For this reason, the plunger 14 is maintained without the looseness at the mounting thin plate 25 of a spring member 7, body vibrations of a vehicle mounting the head lamp transmitted to the plunger 14 acceleratedly, and the vibrations of the plunger 14 can be prevented. Therefore, since the vibrations of the plunger 14 do not influence via movable shades 10, 11 on a cut line CL of a light distribution pattern, especially on the light distribution pattern LP to make passing-by, the light distribution characteristics can be improved. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
