Airbag device provided to steering wheel

An airbag device provided in a steering wheel, comprising:

• an airbag module containing an airbag cushion and a cylindrical shaped inflator that supplies inflator gas to the airbag cushion;
• a functional component provided between the airbag module and the steering wheel;
• and
• a monolithic mounting member formed of a pressed plate material to which the inflator and the functional component are assembled, wherein the mounting member has formed thereon:
• a retaining part for retaining the functional component;
• and
• a circular through-hole part into which the inflator is press-fit to secure the inflator, the circular through-hole part including:
• a circular hole formed in the mounting member penetrating in an axial direction perpendicular to a center of a bottom surface of the inflator and into which the inflator is pressed;
• and
• an annular rib formed on an inner circumferential edge of the circular hole and pressed onto a circumferential side surface of the inflator, wherein the annular rib is directly connected to the retaining part via a solid wall, the solid wall being parallel to the annular rib and perpendicular to the retaining part.

• and
• a monolithic mounting member formed of a pressed plate material to which the inflator and the functional component are assembled, wherein the mounting member has formed thereon:
• a retaining part for retaining the functional component;
• a flat part parallel to the retaining part;
• and
• a circular through-hole part into which the inflator is press-fit to secure the inflator, the circular through-hole part including:
• a circular hole formed in the mounting member penetrating in an axial direction perpendicular to the flat part and into which the inflator is pressed;
• and
• an annular rib formed on an inner circumferential edge of the circular hole and pressed onto a circumferential side surface of the inflator, wherein the annular rib is directly connected to the retaining part via a solid wall extending from the flat part to the retaining part.
