PURPOSE:To provide a lens driving mechanism of a variable light distribution lighting fixture for vehicle which is of a simple and small size structure, and can displace accurately. CONSTITUTION:While a bulb 5 is provided in front of the optical axis L of a reflector 2, so as to radiate a parallel light flux, a fixed lens 6 in which cylindrical lens steps 7 and 10 extending vertically are composed, and a movable lens 9 are provided at the front side on the optical axis L. The movable lens 9 is installed displaceable in the optical axis direction to a lamp body 1 through a parallel link 11, and the forward radiating light flux is made in a focus light or a diffused light by driving the parallel link 11 by an actuator 19, so as to displace the movable lens 9 to a present position. |
