PROBLEM TO BE SOLVED: To establish an economical manufacturing method for a surface skin allowing effective formation of a cleavage-expected part when the surface skin is formed by vacuum molding and not requiring any expensive device for formation of the cleavage-expected part. SOLUTION: When a surface skin for a cabin side member having an air bag door is to be formed by vacuum molding, a surface sheet 11 is heated for softening and sucked to a die 30 for giving the intended shape, and in this sucked and held condition, the position on the surface skin 10 where a cleavage- expected part 20 is provided relative to the air bag door of the surface sheet is pressed by a processing cutter blade 40, and thus the groove-shaped cleavage- expected part 20 is formed. |
