PROBLEM TO BE SOLVED: To shape an airbag to gain the perimeter by sufficiently expanding with respect to fixation into a hollow tubular structure.SOLUTION: The apparatus is formed from an airbag 2, a support post 3 and a cover 4 and carries a material from the outside of a hollow tubular structure 45 through a hole 46 formed on a sidewall of the hollow tubular structure 45 into a space 47 within the hollow tubular structure 45. In the apparatus, the airbag 2 includes: a hollow bag body 11; a support part 11 which is provided in such a manner that the support post 3 can be supported in one end portion of the bag body 11; a support part 13 which is provided so as to support the support post in another end portion of the bag body 11; and a plurality of hollow expansion parts 14 protruding outside from the bag body 11. The plurality of expansion parts 14 extend towards the one end portion and the other end portion of the bag body 11 and are disposed around the bag body 11, such that the airbag 2 is shaped to gain the perimeter. |
