PROBLEM TO BE SOLVED: To prevent the occurrence of differences in the size and appearance of a side winker 1 caused by the thermal shrinkage of a lens part 2 when the lens part 2 and housing 4 molded primarily, after being joined together together, are integrated to produce the side winker 1. SOLUTION: When the lens part 2 and the housing 4 are engaged, by extruding/biasing the lens part 2 outward, a space S formed between the mold surface Ya of a mold Y and a lens peripheral surface 2c by thermal shrinkage is eliminated, and secondary injection is carried out while the lens part 2 is brought into contact with the mold Y, so that the side blinkers which are uniform in size and excellent in appearance are produced.
