Claims

[Claims for Utility Model Registration] A reflecting mirror having a reflecting surface in the shape of a paraboloid of revolution, a light source provided inside the reflecting mirror and emitting a passing beam, and a light shielding means for blocking the front and lower sides of the light source. and a lens attached to cover the entire surface of the reflecting mirror, and the reflecting mirror is configured such that the light emitted from the light source is blocked by a light blocking means to eliminate at least a part of a portion that becomes a shadow. A vehicle headlamp characterized in that the light source axis is offset downward with respect to the lens center position.
