Since an airbag module is supported in an interior of a steering wheel via an elastic body so as to be capable of vibrating, the airbag module vibrates while deforming the elastic body to thus function as a dynamic damper, thereby enabling vibration of the steering wheel to be suppressed. Since the elastic body is formed from a support pin itself, which supports the airbag module on the frame of the steering wheel, compared with a case in which the support pin and the elastic body are formed from separate members, it is possible to reduce the number of components and the number of assembly steps. A part of the support pin may form the elastic body, and the entirety of the support pin may form the elastic body.
