出来るようになる。The support pin 1 is formed into a rod shape having an appropriate length, and is attached to the lower part of the other side of the lamp unit, that is, opposite to the one side of the lamp unit where one aiming moving point (for example, left and right aiming moving point) Q2 is installed. the base end 1a thereof is fixed to the vehicle body B side with a nut 7,
The lower part of the other side of the lamp unit A is supported by the tip part 1b. At this time, the tip 1b of the support pin 1
Although it is possible to directly contact and support the lower surface of the other side of the lamp unit A, it is preferable to support it via the bottle holder 8 fixed to the lower surface of the other side of the lamp unit A as in the illustrated embodiment. is preferred. This bottle holder 8 is made of a resin material such as nylon, and has a support part 8a for inserting and supporting the tip end 1b of the support pin 1, and a mounting part 8b for inserting and fixing into the mounting hole 9 of the lamp unit A. Furthermore, an insertion hole 81a is formed in the support portion 8a to be wide in the direction perpendicular to the support pin 1 so as to accommodate the aiming movement of the lamp unit A in the left and right direction, and
The - of the lamp unit A is located above and below the inner surface of the insertion hole 81a.
A bulging portion 82a is formed to face the support pin 1 in an axial direction in an arc shape so as to correspond to the downward aiming movement. Therefore, we decided to fix the bottle holder 8 to the mounting hole 9 formed in the lower surface 10 on the other side of the lamp unit, and to insert the tip 1b of the support pin 1 into the insertion hole 81a of the support part 8a. The lamp unit L-A is firmly supported by the 6 support pins 1 without wobbling when subjected to vibrations, and when adjusting left/right and up/down aiming, the bottle holder 8 is in the same position as the movement of the lamp unit A. !・In addition to being able to move freely back and forth and left and right within the insertion hole 81a with respect to the bottle 1, the inner surface of the insertion hole 8 of the bottle holder 8 is also resistant to tilting of the lamp unit in the front and back direction, especially when adjusting the aiming in the vertical direction. This can be followed by the bulging portions 82a formed in a vertically opposed manner, making it possible to follow and respond to flexible movements accompanying aiming adjustment.
