Claims

[Scope of utility model registration request]

A piston rond that is reciprocated in the axial direction by a motor and a headlamp that is tiltably supported are connected via an adjustment screw and a nut member, and a ferrite core is attached to the piston rond, and the piston rond is A hollow coil is installed concentrically with the rond, and the ferrite core is configured to move in and out of the hollow coil as the piston rond moves forward and backward, and changes in inductance of the hollow coil due to the movement of the ferrite core in and out are detected. An optical axis adjustment device for a headlamp, characterized in that a means is provided to detect the position of a piston rond.
