PROBLEM TO BE SOLVED: To reduce occupied space of a lighting fixture including a mechanism for adjusting a reference position of an optical axis.SOLUTION: A lens holder 13 holds a projection lens in which at least one part of light emitted from a light source passes. First members 13d1 and 13e1 have an axis B. Second members 31 and 32 hold the first members 13d1 and 13e1. A first screw 81 adjusts a reference position of an optical axis A of the projection lens related to a vertical direction. A second screw 91 adjusts a reference position of the optical axis A related to a horizontal direction. The first members 13d1 and 13e1 are arranged so that the axis B is located on a surface which is orthogonal to the optical axis A and which intersects a focal point F of the projection lens. Both the rotation action of the first screw 81 and the rotation action of the second screw 91 are applied on the first members 13d1 and 13e1. |
