PURPOSE:To ensure the manual raise and turn-down actuation by connecting one end of a flexible wire with the rotating shaft of a motor which raises and turns down a head lamp by way of a detachable coupling whereby providing a rotation actuating knob to the other end of the wire. CONSTITUTION:When a motor 21 is driven, a motor link 24 is rotated by way of an output shaft 22, and simultaneously, a link rod 25 is operated reciprocally for raising up and turning down a head lamp. In this case, if the motor 21 fails, th head lamp is raised or turned down manually by means of an actuating knob 37. That is, the actuating knob 37 is pushed onto a stationary member (35) side first, then a socket 33 is coupled with the end section of the output shaft 22 overcoming a spring 30 by way of a flexible wire 31. Subsequently, the actuating knob 37 is rotated for rotating the output shaft 22 so as to rotate the motor link 24 in a similar manner that the motor 21 drives, and simultaneously, the link rod 25 is operated reciprocally for raising up and turning down the head lamp. |
