车辆用前照灯
摘要：
本发明提供一种车辆用前照灯，具备半导体型光源（2U、2D）、具有反射面（10U、10D）的固定反射器（3）、具有反射面（12U、12D）的可动反射器（4U、4D）、螺旋管（5）和驱动力传递机构（6）。驱动力传递机构（6）包括弹性变形的齿条（14）和齿轮（15U、15D）。齿条（14）的两端部的齿部（17U、17D）的高度（H1）高于齿条（14）的中间部的齿部（17U、17D）的高度（H2）。其结果，本发明能够较小地维持齿条（14）和齿轮（15U、15D）之间的负载，并且，能够高精度地维持可动反射器（4U、4D）的停止位置的位置精度。
摘要（英）：

The present invention provides: semiconductor-type light sources; a fixed reflector having reflection surfaces; movable reflectors having reflection surfaces; a solenoid; and a driving force transmission mechanism. The driving force transmission mechanism is made of: a rack that is elastically deformable; and pinions. A height H1 of a respective one of gear portions at each end part of the rack is greater in comparison with a height H2 of a respective one of gear portions at an intermediate part of the rack. As a result, the present invention is capable of maintaining a load between the rack and a respective one of the pinions at its required minimum level, and is capable of maintaining positional precision in stop location of the movable reflectors at high precision.
