  By the way, in recent years, as a lens for a vehicle headlamp, in addition to a main lens for a projector lamp, for example, a sub lens for a position lamp or a sub lens for a daytime running lamp may be required. is there.

  Conventionally, such a main lens, a sub lens, and a holder for holding them have been formed and assembled as separate parts, but in order to reduce the assembly cost of a vehicle headlamp. In addition, for example, it is conceivable to integrally mold the main lens, the sub-lens, and the holder using a molding apparatus as described in JP-T-2005-527072.

  Specifically, when the main lens, the sub lens, and the holder are integrally formed, the sub lens needs to be formed of a transparent or translucent material, and is located between the main lens and the light source in the holder. The part needs to be formed of an opaque material in order to prevent leakage of light emitted from the light source.

  Therefore, for example, when a main lens, a sub lens, and a holder are integrally formed using a molding apparatus as described in JP-T-2005-527072, a gold for molding a transparent or translucent sub lens is used. It is necessary to separately provide a mold and a mold for forming an opaque holder.

  As a result, for example, when the main lens, the sub lens, and the holder are integrally molded using a molding apparatus as described in JP-T-2005-527072, the operator or the like molds the translucent sub lens. The molded product must be removed from the mold for mounting the molded product on the mold for molding the opaque holder.

  In view of the above problems, the present invention integrally molds the main lens, the sub lens, and the holder without requiring the operator to remove the molded product that has not been integrally molded from the main lens, the sub lens, and the holder from the mold.
