A damper structure provided in a steering wheel of a vehicle to be able to achieve an improved effect of reducing vibration in a low frequency region and structurally prevent noise generation. The damper structure includes a plate member which faces the steering wheel and to which an airbag module is to be attached, an insulator attached to the plate member, a connector inserted into the insulator and having one end fixed to the steering wheel to be oscillated by vibration of the steering wheel, an elastic member surrounding the connector in the insulator, a ring provided with the elastic member to transmit the oscillation of the connector to the elastic member, a stopper provided around another end of the connector to face the elastic member, and a coil spring which brings the elastic member of the insulator into pressure contact with the stopper.

A steering wheel includes a decorative component and a surface skin on a surface of the rim. The decorative component is formed into a band and a leading-end portion of the decorative component has a tapered form in which an inner edge curves towards an outer circumference of the rim and serves as a curving edge. The surface skin includes a curved-side section adjoining the curving edge and a non-curved-side section adjoining a non-curving edge of the leading-end portion. The curved-side section includes a main body that includes a curving portion which corresponds to the curving edge of the leading-end portion in shape, and an extended portion that extends beyond an apex of the leading-end portion and extends towards the non-curving edge of the leading-end portion of the decorative component. A region of the extended portion beyond the apex is joined to a leading edge of the non-curved-side section.
