A grab rail is attached via a bracket to an upper portion of a side panel inside a vehicle, and a curtain-shaped airbag is arranged in a folded state on a side portion of the side panel inside the vehicle. The bracket includes a vehicle body attachment seat section that is attached to an attachment surface formed on the side panel; an arm section that is bent from the vehicle body attachment seat section and extends downward and inward in the vehicle width direction; and a grab rail attachment seat section that is bent from a lower end of the arm section, extends upward and inward in the vehicle width direction, and has the grab rail attached thereto. A space section formed by the side panel and the arm section opens downwardly and serves as a storage portion for receipt of the folded curtain-shaped airbag.
