Abstract
A method for forming tear lines in the rear side of an automobile interior article having a cover portion being developed from which an airbag inflates. When either an automobile interior article body having an integrally molded surface portion or an automobile interior article surface portion is to be molded, the mold is opened after tear line forming projections are moved forward and backward with the mold closed. Thus, the tear lines can be formed at the molding time without any visible extrusion marks of the tear line forming projections on the front surface side (the design face).
