PROBLEM TO BE SOLVED: To easily control exhaust gas inside an airbag. SOLUTION: An opening part 50 is formed on a rear wall part 14C of an airbag case 14, and an exhaust pipe 12B of the airbag 12 is inserted to the opening part 50. An exhaust door 58 is slidable by a guide 54. When it is required to increase internal pressure of the airbag 12 during deployment of the airbag 12, the exhaust door 58 is closed to press an intermediate part of the exhaust pipe 12B by the exhaust door 58, preventing passing of gas. Thus, the internal pressure of the airbag 12 is controlled to become high. In contrast, when it is required to decrease the internal pressure of the airbag 12 during deployment of the airbag 12, the exhaust door 58 is opened to prevent the intermediate part of the exhaust pipe 12B from being pressed by the exhaust door 58, enabling exhaust gas to outside. Thus, the internal pressure of the airbag 12 is controlled to be low. COPYRIGHT: (C)2008,JPO&INPIT
