Disclosed herein is an airbag device including a tether attached to an airbag for determining an expansion shape of the airbag. The tether is formed in such a manner that the expansion length of the middle part of an airbag is shorter than the expansion length of both side edges of the airbag when the airbag is expanded, whereby direct contact between the chest or the head of a passenger and the airbag is prevented. Consequently, the passenger is not injured by a punch-out-force created by sudden expansion in the central region of the airbag when the expansion of the airbag is initiated. In addition, the passenger is not subjected to the pressure of the airbag, and the passenger is nestled in the airbag, whereby the passenger is not out of the protection range of the airbag even when a vehicle is rocked from side to side after the airbag has been expanded.
