The invention relates to a double-color covering car lamp light distribution mirror suction-shrinkage prevention structure. The suction-shrinkage prevention structure comprises a primary forming structure and a secondary forming structure, wherein the primary forming structure is provided with a foot portion which protrudes and extends laterally; the suction-shrinkage prevention structure furthercomprises a prefabricated member, wherein the prefabricated member is pre-buried in the inner side of the foot portion of the primary forming structure and protrudes towards the secondary forming structure; and the material of the prefabricated member and the material of the secondary forming structure are fused together, so that the position, corresponding to the foot portion, of the secondary forming structure is flat without suction-shrinkage. Through the suction-shrinkage prevention structure, a secondary product is formed on a primary product and covers the primary product completely, sothat the prefabricated mem
