An air bag 1 has a mounting piece 3a having an insert hole 4 arranged in a position corresponding to each locking hole 28. A lid body 9 has a door part opened when an air bag is expanded, and a cylindrical part 14 arranged around the door part and protruded to the flange part 27a side. A locking leg 16 inserted to and locked to each locking hole 28 through the insert hole 4 and a contact surface 18 making contact with the periphery of each insert hole 4 of the mounting piece 3a when the locking leg 16 is engagingly locked by the locking hole 28 are formed on the lower surface of the cylindrical part 14. The lid body 9 and the air bag 1 are assembled and held to the case 23 by the insertion and engaging locking of each locking leg 16 by the locking hole 28 through the insert hole 4. |
