Lens in vehicular lamp, method of shaping the lens and an apparatus for shaping the lens

摘要

A lens 1, for use in a vehicular lamp, including a front section 4 directed generally to the front, a curved section 5 extending from the front section 4 and changing direction to face laterally and seal legs projecting generally to the back from the peripheral edges. The seal leg in the curved section has a portion that extends inwardly to form an undercut in the direction in which the lens is removed from a lens shaping mold. The curved section 5 is shaped from resin in at least two colors and the seal legs which at least form an undercut in the curved section are shaped from a resin having one of said at least two colors. Thus the lens can be shaped in a mold of a simplified structure.
