Claims

[Scope of utility model registration request]

A cylindrical nut holding part having a groove-shaped opening on one side and a hole of an appropriate size on the other side is provided as a movable part for adjusting the optical axis and on the back side of the reflector to hold the nut. A nylon nut is integrally formed with a spherical part that fits into the opening and faces the hole, and a rectangular block that fits in the opening.
An optical axis adjustment device for a headlamp, characterized in that a screw hole passing through the block body from the spherical portion is provided, and an adjustment bolt passing through the housing is screwed into the screw hole.
