摘要： PURPOSE:To perform the analogue indication of the variation and direction of the slant of optical axis of a head lamp and enable the indication of correcting state of the optical axis by detecting optically the variation of relative position between the car body and the front and rear wheels in the vertical direction. CONSTITUTION:Light receiving elements 301-303 are arranged on a line in the vertical direction, opposed to the other end of optical fibers 71 and 72 on the wheel side. These are retained on the fornt wheel 4 side of the car body 1 and connected to an output circuit 31 comprising an operating power supply, and further, light emitting elements 321-323 are connected to the output terminals corresponding to the light receiving elements 301-303 of this output circuit 31. The light emitting elements 321-323 are arranged in the vertical direction on the front surface of a panel plate 12 on the driver's seat side and opposed to the indication ''UP'', ''O'', ''DOWN'' from the back of a scale plate 18. In this case, the states of slant of the optical axes of head lamps 6a and 6b are displayed through the luminescence of the light emitting elements 321-323.
