<p>PROBLEM TO BE SOLVED: To provide a vehicle head light which inhibits temperature rise of an actuator and thereby secures good operation state of the actuator without causing enlargement and cost increase.SOLUTION: A vehicle head light includes: a movable shade 14 which controls a shielding amount of light emitted from a light source 13b; an actuator 21 which actuates the movable shade; a heat sink 15 to which heat generated in the light source during driving of the light source is transmitted, the heat sink 15 emitting the transmitted heat to inhibit temperature rise of the light source; and a fan 22b which generates cooling air for promoting heat emission from the heat sink. Rotations of the fan causes a part of the cooling air to flow from the fan toward the actuator or from the actuator toward the fan.</p> |
