Abstract
Mounting portions of an air bag body are respectively nipped by positioning plates which are each fastened and fixed to a pillar inner panel by a weld nut and a bolt via the plates. Caulking portions are formed on the plates so that the mounting portions of the air bag device are in advance fixed between the plates. A convex portion is formed on the plate, and with the convex portion being engaged with a hole formed in the pillar inner panel, relative rotation of the plate and a vehicle body is prevented. As a result, rotation of the air bag body in a direction in which the mounting portions are fastened, which occurs during mounting of the air bag body to the vehicle body, can be prevented.
