<p>PURPOSE:To facilitate the adjustment work, and prevent the damage of an adjusting shaft by providing an engagement part at a position projecting upward or downward from the upper edge or the lower edge of a mounting ring, and engaging a second aiming adjusting shaft with the engagement part. CONSTITUTION:When a second aiming adjusting shaft 8 is screwed to a nut or screwed back from the nut, a mounting ring 4 and a lamp unit 2 are turned nearly upward or downward around of a straight line B-B, which connects a point for connecting a first aiming adjusting shaft 7 and a left side connecting lug and a point for connecting a tension spring 9 and the mounting ring 4, and the illumination direction of the lamp unit 2 is thereby adjusted in the same direction.</p> |
