<p>PURPOSE:To increase the freedom of the provision direction of a zero point regulating shaft by supporting inclination-movably against a reference member arranged on an inclination-moving member back side, by means of an aiming mechanism, the inclination-moving member having a light reflection surface setting a lamp illuminating shaft. CONSTITUTION:A reflector 14 is supported by the 3 points of one swing support point 20 arranged at the right angle top position of a right-angled triangle when viewed from the front, and by right and left aiming points 30, 40 arranged at other top positions. The point 20 is of a ball joint structure in which a spherical portion 22 provided at a lamp body 12 is supported by a socket 24 on a reflector 14 side, and the position against the body 12 is at a fixed condition. Meanwhile, aiming points 30, 40 are of a structure in which aiming screws 32, 42 that are supported at the body 12 turnably respectively, are screwed by nuts 34, 44 on the reflector 14 side respectively, and nuts 34, 44 swing forward and backward along screws 32, 42 by conducting the turning operation of screws 32, 42, and as a result, it is arranged that the distances of aiming points 30, 40 from the body 12 are changed.</p> |
