PURPOSE:To contrive to widen the field of vision of a driver during the night and to ensure the safety in a curvilinear driving by a method wherein head lamps are rotated by means of the oil pressure within a cylinder produced by the motion of a piston, which is caused by the turning of the steering wheel. CONSTITUTION:A worm gear 2 moves a side body 3 vertically by turning the steering wheel 1 right and left. A piston 4 is also moved vertically with the vertical motion of the side body 3. The oil pressure within the cylinder 5 is changed by the piston 4 and applied to fine pipes 6 to move the fluids in the pipes 6. Consequently, the oil pressure within a lamp side cylinder 7 is changed, resulting in moving a piston 8 vertically in order to transmit the motion of the piston 8 to a moving shaft 9. A fixed shaft 10 is fixed in such a range not to disturb the rightward and leftward motion of a lamp 11. Accordingly, the motion of the moving shaft 9 around the fixed shaft 10 causes the lamp 11 main body to move right and left in the directions as indicated with the arrows C and D. |
