PURPOSE:To prevent the generation of abnormal noise due to the shift of an air bag. CONSTITUTION:Each unevenness is formed on an air bag 15 and the slide contact part between a back-up plate 13 in which the air bag 15 is accommodated and a cover 16, and a recessed part 20 is formed on the back-up plate 13, and the shift of the air bag 15 is regulated by the unevenness part engagement. Further, an elastic member 40 is installed on a back-up plate 33, and an air bag 35 is press-attached on the inner surface of a cover 36, and the shift of the air bag 35 is regulated. Further, the frictional coefficient is increased by applying rubber coating 50 on the cuter surface of an air bag 45, and the slide between the inner surface of a back-up plate 43 is regulated. |
