<p>PURPOSE:To constantly irradiate the advancing direction of an automobile regardless of whether the automobile is traveling straight or curvedly by connecting a piston of a hydraulic cylinder to a head lamp of the automobile together with actuating a pump as a steering wheel is manipulated, thereby supplying the oil pressure to the hydraulic cylinder. CONSTITUTION:A hydraulic pump 1 is connected by an oil passage to a hydraulic, handle-operating cylinder 2, while this cylinder 2 is connected by an oil passage to a 3-position electromagnetic valve 3. In addition, the valve 3 is connected via each oil passage to both right and left hydraulic cylinders 5, while a pin 8, which is provided to a piston 18 of each hydraulic 5, is connected by an installing arm 9 to a pin 9 of a light 6. When the steering wheel is manipulated, a pump 1 is actuated by the operating cylinder 2, while a working, electromagnetic valve 16 is switched by the ON-operation of a switch 15. With this contrivance, the oil pressure from the pump 1 is supplied first to the valve 3 and next to the hydraulic cylinder 5 via a hose 13. Thus, the direction of the light 6 can be changed by the piston 18.</p> |
