PROBLEM TO BE SOLVED: To provide a knee airbag device capable of: directing the flow of an inflator gas injected from an inflator into an airbag, reliably toward the opening side of a housing, thereby to prevent the contact of the airbag with the housing; and extending and expanding the airbag properly to the outside of the housing thereby to retain the knee part protection function of a passenger sufficiently.SOLUTION: A housing 1 of a hollow box body shape having an opening 1a to be closed in an openable manner by a door part 2a is equipped therein with a gas deflecting member 9 of a plate wall shape disposed between an inflator 4 and a rear side wall part 1c and formed to have such a size B as to overlap the inflator along the depth direction of the housing from the side of a mounting wall part 1e to the opening side thereby to direct the flow of the inflator gas to be blown from the inflator into the inside of an air bag 3 toward the opening side.SELECTED DRAWING: Figure 3 【課題】インフレータから噴出されてエアバッグ内部に噴き込まれるインフレータガスの流れを、確実にハウジングの開口側へ向かわせることが可能で、エアバッグのハウジングへの接触を防止し、かつエアバッグをハウジング外方へ適切に展開膨張させて、乗員の膝部保護機能を十分に確保することができるニーエアバッグ装置を提供する。【解決手段】ドア部２ａで開口１ａが開放可能に閉じられる中空箱体状のハウジング１内部に、インフレータ４と後方側壁部１ｃとの間に配置され、取付壁部１ｅ側から開口側へ向けて、ハウジングの深さ方向に沿ってインフレータとオーバーラップする寸法Ｂで形成されて、インフレータからエアバッグ３内部へ噴き込むインフレータガスの流れを開口側へ向かわせる板壁状のガス変向部材９を備えた。【選択図】図３
