PURPOSE:To insert an optical axis adjusting mechanism assembled to a reflector into the inside of a housing and thereby aim at the promotion of easiness for installation, by making a maximum diameter of an adjusting member to be projected outward the housing of an all-direction adjusting mechanism smaller than that of a setting hole of the housing. CONSTITUTION:In order to assemble an optical axis adjusting mechanism A' to the inside of a housing 50, a bracket 61 of a turning fulcrum mechanism 60, a spherical body 62, a vertical direction adjusting mechanism 80 and a compensation mechanism 90 are all assembled to a reflector 52. Here, an adjusting bolt 76 and an adjusting shaft 84 are inserted into a female screw part 75 and a keyway hole 86 of a screw rod 83 in advance. Next, the spherical body 62 is pivoted on a receiving part 63, while the reflector 52 and the optical axis adjusting mechanism A' are inserted into the housing so as to make the adjusting bolt 76 and the adjusting shaft 84 insertable into setting holes 53 and 54. And, when each of clips 103 and 104 is inset in between the adjusting bolt 76 and the adjusting shaft 84 being projected outward the housing 50 and locked to each of clip locking parts 55 and 56, assembling operation is performable in a simple manner without necessitating jigs and the like. |
