Abstract
A variable light distribution type automobile lamp capable of varying the range of diffusion of a flux of light by changing the position of one of two cylindrical lenses. Flat areas are formed at the centers of both lenses to produce a spot beam at the center of the ouput light flux. The lenses are aligned with one another using this spot beam. The invention also provides a device for varying the distance between the lenses in the direction of the optical axis without rotating the lenses relative to one another.
