    摘要： [Problem]
    Gas is properly fed into a head facing portion while upsizing of an inflator is prevented.
    [Solution]
    Throttle portions 51 are provided for coupling between a frontal side and a backside of an airbag 40 between a neck portion 41 and a head facing portion 42. Seams 51A are formed as contours of the throttle portions 51 positioned outermost the airbag 40 in a width direction. The seams 51A are parallel to side edge portions 40L, 40R of the airbag 40 positioned outside the seams 51A in the width direction. Seams 51B are formed as contours opposed to the throttle portions 51 arranged adjacent to each other. The seams 51B are approximately parallel to each other.
