PROBLEM TO BE SOLVED: To solve a problem that, in making dust doubling between cover lenses of a headlight and a taillight and a car body, a car body side formed of metal and a cover lens side formed of resin tend to have some differences in shape or the like by a molding state, and therefore, there has been a difficulty in the past in a dust doubling process. SOLUTION: In the vicinity of an outer periphery edge part 1b of a lens face part 1a of the cover lens 1, a groove part 3 of a nearly semicircular shape is provided along the outer periphery edge part at a constant distance, so that little shrink toward the lens face part 1a and the outer periphery edge part 1b takes place at molding of the cover lens, enabling to reduce disorder of the size and shape to improve in accuracy, which makes mismatch of dust less conspicuous and a dust-doubling work can be simplified.
