<p>PURPOSE:To make a head lamp compact by arranging a swing support point at the position of a top other than tops confronting the oblique sides of a triangle formed by a swing support point and aiming points. CONSTITUTION:A reflector 14 is supported by the 3 points of one swing support point 20 and two aiming points 30, 40 arranged at the respective top positions of a right-angled triangle which is so when viewed from the front, and the support 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 respectively supported at the body 12 turnably, are respectively screwed by nuts 34, 44 on the reflector 14 side, and nuts 34, 44 swing forward and backward along screws 32, 34 as screws 32, 34 are subjected to a turning operation, and as a result, the distances of points 30, 40 from the body 12 are changed.</p> |
