<p>PURPOSE:To enable high-precise rotation of a moving reflection mirror, by a method stationary and moving reflection mirrors pointing to the direction of a main optical axis are situated in a single light chamber, and the moving reflection mirror is rotated through a counter belt through drive of a drive part. CONSTITUTION:When a title light tool is applied for a light tool having both fog lamp and cornering lamp functions, a box type lamp body 2 the front of which is opened approximately in a rectangular shape is provided, and a lens 3 is mounted to the opening part. A stationary reflection mirror 4 formed with a frameform front part 5 and a backwardly recessed reflection part 6 and a moving reflection mirror 10 formed with an oblong reflection part 11, being long lengthways as seen from the front, and mounting pieces 12a and 12b, protruded from upper and lower ends toward the front, are contained in the lamp body 2. A bulb 16 is positioned so that a filament 18 is situated in the focus position of the reflection parts 6 and 11. The moving reflection mirror 10 is rotatable through a counter belt 46 run around toothed pulleys 33 and 34 through the working of a drive part 19.</p> |
