<p>PURPOSE:To restrain the frequent variation of an illuminating direction by applying the passage range of an origin zone as the prevention range of an illuminating direction variable operation in the constitution wherein the illuminating direction of a lighting means is varied interlocked with handle steering. CONSTITUTION:In the constitution wherein the illuminating direction of a lighting means such as a head lamp is made variable interlocked with handle steering, the illuminating direction variable operation of the head lamp is prevented when a steering angle is zero, or within a range W equal to or smaller than the predetermined steering angle in right and left directions from the starting point of a handle at a straight forward steering position. In this case, the illuminating direction of the head lamp is fixed toward the front direction of a vehicle. Or the aforesaid range W is determined as the passage range of an origin zone detected with the handle steering and when a steering angle is out of the range W, the illuminating direction is varied linearly, interlocked with the handle steering.</p> |
