PROBLEM TO BE SOLVED: To certainly hold airtightness inside of an air bag and to certainly actuate the air bag in comparatively simple constitution. SOLUTION: Inner bushes 24 outside diameters of which are larger than that of a gas generator 20 are respectively interposed between the neighbouthood of both ends in the longitudinal direction on an outer surface 21 of the gas generator 20 and an inner surface of an air bag 10. Consequently, a required space is made between a gas blowout hole 22 of the gas generator 20 and the inner surface of the air bag 10. Additionally, the inner bushes 24 and outer bushes 27 are fastened from the outer surface side of the air bag 10 by a fastening part of an outer housing 30. Consequently, a gas generator installation part 13 of the air bag 10 is bent in a cross sectionally crank shape and fastened, and airtightness in the air bag 10 can be certainly held. |
