A knee protecting airbag device includes a folded airbag housed below a member attached to the vehicle body and in front of the knees of a seated passenger. The airbag extends and expands when fed with an inflating gas toward the rear of the vehicle to protect the knees of the passenger. The airbag includes a lower expansion portion, which is upstream in the flow of the gas, and an upper expansion portion, which is downstream. The lower expansion portion protrudes toward the rear of the vehicle to protect the knees. The upper expansion portion protrudes upward from the lower expansion portion. The airbag properly protects the knees of the passenger by extending and expanding efficiently, taking into account the time elapsed, until completion of the extension and expansion.
