1. A head protecting airbag device comprising:
an airbag that is configured to cover a window of a vehicle when being unfolded and inflated, and that is folded and stored on an upper edge side of the window on an interior vehicle side;
an inflator that has a substantially cylindrical outer shape of which an axial direction is disposed substantially along a front-rear direction and that supplies inflation gas to the airbag; and
an attachment bracket that attaches the inflator to a body side on the upper edge side of the window, wherein:
the attachment bracket is made of sheet metal,
the attachment bracket includes
a holding portion that
is formed by being curved in a substantially arc-shaped cross section so as to substantially follow along an outer peripheral surface of the inflator,
is disposed so as to partially cover the outer peripheral surface of the inflator, and
is configured to be capable of holding the inflator using a clamp disposed so as to surround an entire circumference in a circumferential direction on an outer peripheral side of the inflator, and
an attachment piece portion that is formed so as to extend from an end edge of the holding portion on an exterior vehicle side and that is attached to the body side using a bolt,
the holding portion is disposed so as to cover and support a lower surface side of the inflator, as viewed in cross section in the axial direction of the inflator, in a state where the airbag device is mounted in the vehicle, and
in the attachment bracket, a reinforcing protrusion-shaped portion that partially protrudes on the interior vehicle side from the holding portion to the attachment piece portion is continuously formed.
