Airbag Cover, Method for Manufacturing Same, and Airbag Device

The present invention provides: an airbag cover which is formed by integrally joining a first base fabric and a second base fabric having mutually different characteristics, and has a joint portion that ensures high productivity in mass production; a method for manufacturing the airbag cover; and an airbag device. The present invention relates to an airbag cover for storing a bag-shaped cushion which is rolled up or folded before being inflated and deployed by a gas supplied from an inflater, and relates to a method for manufacturing the airbag cover. The airbag cover is characterized by comprising a first base fabric made of a plain-woven fabric or a non-woven fabric made from chemical fibers, and a second base fabric containing fibers different from the fibers constituting the first base fabric, and having an initial tensile resistance value higher than an initial tensile resistance value of the first base fabric.
