A module case is provided in which an air bag module is housed. The air bag module is arranged inside of a seat back of a seat of a motor vehicle and the lid of the module case is opened by a pressure of an air bag which inflates at the side collision of the motor vehicle, so as to deploy the air bag from the lid into a passenger compartment of the vehicle. Even when the lid has become unopenable due to the depression thereof by a door deformed by the shock of the collision, tear lines formed in a case body of the module case are torn to turn a front wall of the case body in a direction towards the front of the vehicle, and hence, the air bag can be deployed from the front wall part of the case body into the passenger compartment without hindrance.
