Steering wheel and method of manufacturing same

A method of manufacturing a steering wheel including:

• a core bar having a boss section and a base section with a mounting hole and a spring mounting section, a rim section, and a spoke section connected to the rim section and the boss section or the base section;
• the spring mounting section including:
• a main body column section protruding from a base surface of the base section and an extension connected to the main body column section and extending from the main body column section;
• the method comprising:
• a step of molding a back cover of resin material on a back side of the core bar where the leading side of the extension is not connected with the base section;
• a step of attaching a retaining spring to the back side of the core bar to which a back cover was molded, including:
• positioning the mounting section of the retaining spring between the base surface and the extension, attaching the spring mounting section so as to sandwich the main body column section, providing a configuration to prevent retraction of the retaining spring from the mounting section, and positioning the pin engagement section of the retaining spring in the mounting hole;
• and
• a step of assembling an airbag module to the front side of the core bar, including:
• inserting a pin provided on the airbag module into the mounting hole and engaging the pin with the pin engagement section of the retaining spring.
