An insertion hole of the gas generator is formed, the gas generator is inserted from an opening formed on one end surface of the storage container, is inserted into the insertion hole of the partition wall, and is provided at the tip of the insertion side of the gas generator. Since the bolt portion is tightened and fixed by the nut member through the bolt insertion hole formed on the other side end surface of the storage container,
A gas generator can be stably held, a plurality of airbag main bodies are respectively fixed to the plurality of small chambers, and the gas ejected from the gas generator by the partition wall is a plurality of airbags from the plurality of small chambers. Since it is designed to be supplied to the main body, a plurality of seated persons can be restrained and protected by the plurality of airbag main bodies, and the airbag main body is small in size and can be easily sewn and folded. It can be inserted stably, and the tip of the bolt can be easily inserted into the insertion hole on the side of the storage container, improving the workability of assembly, and the airbag body is folded and stored in the storage container. It can be assembled while maintaining the condition, work efficiency can be improved, the storage container can be made smaller and lighter, the cost can be reduced, and the occupant can be restrained by the airbag body. It is possible to improve the performance.
