A folded-up air bag is accommodated in a module cover of a steering wheel, and a peripheral edge of an opening in the air bag is fixed to a retainer supporting an inflator. The folded-up air bag is covered from a rear side of a vehicle to a front side of the vehicle by a deployment-limiting sheet disposed along an inner surface of the module cover and fixed at one end thereof to the retainer. The deployment-limiting sheet is longer than a length of an inner periphery of the module cover in a longitudinal direction of the vehicle body. Thus, it is possible to inhibit the air bag from being expanded rearwards of the vehicle body at an initial stage of deployment by the deployment-limiting sheet, thereby avoiding the early interference with an occupant.

1. An air bag device for a vehicle, comprising:a folded-up air bag accommodated in a module cover of a steering wheel; a peripheral edge of an opening in the air bag being fixed to a retainer supporting an inflator so that when the air bag is expanded by a gas generated by the inflator, the air bag deploys into a vehicle compartment through an opening in a lid provided on the module cover; and a deployment-limiting sheet disposed between the folded-up air bag and an inner surface of the module cover and which is longer than a length of an inner periphery of the module cover in a longitudinal direction of the vehicle; said deployment-limiting sheet having one end fixed within the steering wheel, and the folded-up air bag being covered on a front side of the vehicle, extending from a rear side of the vehicle, by a free end of said deployment-limiting sheet; and said deployment-limiting sheet covering a lower rear portion of said air bag and extending between said air bag and an object to be restrained by the air bag during an initial stage of air bag deployment, such that said air bag deploys primarily upwardly during the initial stage of air bag deployment.
