A knee protection airbag device includes an airbag. When the airbag is housed, the occupant side wall portion and the vehicle body side wall portion overlap and spread flat, and are curled and foldedsuch that the upper edge side of the knee receiving portion side approaches the lower edge side of the mounting portion side. End-side portions of left and right sides of the crimped folded portion are formed as folded portions that are folded on a central portion near a center of the crimped folded portion in a left-right direction to form a folded complete body. When inflation gas flows into theairbag, and when folding of a first fold is eliminated and the first overlapping portion is separated from a rear region of the central portion, engagement between the first overlapping portion of the airbag and a tip-side portion is released.
