A knee protection airbag device includes an airbag. When the air bag is accommodated, an occupant side wall portion and a vehicle body side wall portion are overlapped and expanded flatly and roll-folding is performed such that an upper edge side of a knee receiving portion side approaches a lower edge side of the mounting portion side, end side portions on left and right sides of the roll-folded roll folding portion are formed as folded portions which fold over a central portion near a center in a left-right direction of the roll folding portion to form a folding completed body. A joining between a first overlapping portion and a tip side part of the airbag is released when an inflation gas flows into the airbag and when a fold of a first fold is canceled and the first overlapping portion deviates from a rear area of the central portion.
