In order to provide a manufacturing technology capable of reliably manufacturing an airbag cover (100) for covering a vehicle airbag (150), an airbag cover (100) is processed with an ultrasonic processing blade (216) and a tear line (102) having a depth in a range of the plate thickness of the airbag cover (100) is formed. At this time, a teaching member (219) profiles along a teaching line (132) which is formed in an airbag cover supporting surface (131) of an airbag cover supporting member (130), such that profiling data is derived and obtained. And then, a profiling teaching step (S10) which teaches a control unit (220) based on profiling data is provided. <IMAGE> |
