PURPOSE:To provide a simple device capable of changing projection angles of a head lamp by operating switches, etc. of a head lamp driving gear on the basis of automatical detection and display of the longitudinal inclination of an automobile body. CONSTITUTION:The vertical displacement A of an axle 22 to a car body is taken out as revolution of a transmission shaft 12 through a connecting rod 16 and an arm 14. Therefore, a swing body 6 swings to a case 1 and the position of a signal formation filter 9 facing an electrode 4 is changed in accordance with the amount and direction of displacement of the axle 22. Accordingly, the signals formed in the filter 9 are indicated on a display part through a optical fiber 24. When an operator rotates a knob 32 looking at this display and reciprocates a connecting member 40 through a screw spindle 41, a piston 38 is reciprocated similarly, the piston 43 of the driving part 35 is reciprocated through liquid pressure in a cylinder chamber 37 and a head lamp 45 is inclined suitably through a rod 44. |
