  "textContent": "Provided is an optical axis adjustment device for a vehicle headlamp. The optical axis adjustment device adjusts an optical axis of a headlamp unit to be mounted in a vehicle, and the optical axis adjustment device includes: an engine temperature acquirer; a displacement amount calculator; a speed information acquirer; and an optical axis adjuster. The engine temperature acquirer acquires a temperature in an engine compartment of the vehicle. The displacement amount calculator calculates a displacement amount of the optical axis based on the acquired temperature. The speed information acquirer acquires speed information including a travel speed and a travel time of the vehicle. The optical axis adjuster adjusts the optical axis of the headlamp unit on a basis of the calculated displacement amount and the acquired speed information.",
