<P>PROBLEM TO BE SOLVED: To provide an interior panel for a vehicle capable of surely opening an airbag door when operating an airbag device without exposing a trace of tear line machining, and its tear line machining method. <P>SOLUTION: A cut 22 of a prescribed depth is given to a rear side of surface skin 11 of the interior panel 1 by a cutting blade T. An adhesion preventing material 32 to prevent adhesion of cutting boundary faces 22a and 22b with each other is interposed between the pair of mutually opposed cutting boundary faces 22a and 22b of the cut 22. As a result, the airbag door 2 can be surely opened when operating the airbag device 3, while maintaining an invisible state without exposing the trace of the tear line machining. <P>COPYRIGHT: (C)2010,JPO&INPIT |
