PROBLEM TO BE SOLVED: To secure the linearity of the crimp of a hinge section when a door opens without problems which may be caused when a door section is mounted. SOLUTION: A slit 18 defining an opening section, from which an air bag body swells, and a door section 16 which closes the opening section is formed in the core material 7 in the back face of an air bag lid section 2, and a plurality of hinge holes 21 are formed in a nearly row-like shape along the boarder section connecting the door section 16 and the opening section to each other, and straight linear beads 24 are formed in the side section of the hinge holes 21.
