A steering wheel in which a load exerted on an elastic member constituting a dynamic damper can be reduced, the life of the dynamic damper can be extended, and the assembly operation is readily performed. The steering wheel has a first horn plate (), a second horn plate (), guide pins (), stoppers (), bushes (), elastic members (), and coil springs (); the bushes () are divided into first bushes () which have first flanges (), openings (), columnar parts (); and recessed parts (), and second bushes () which have second flanges (), openings (, and casings (); and the columnar parts () are configured so as to be in contact with the second flanges ().

Steering wheel

A slideris supported on a holderof a steering wheelvia a coil springso as to be movable in a direction of an axis while an air bag moduleis supported on a slidervia a damper springso as to be movable in a direction perpendicular to the axis. Since the coil springdoes not affect vibration of the air bag modulein the direction perpendicular to the axis, it is possible to set a spring constant of the coil springat a value appropriate for the operation of a horn switch, and to set a spring constant of the damper springat a value appropriate for the operation of the dynamic damper. As a result, it is possible to effectively reduce the vibration of the steering wheelin the direction perpendicular to the axis with the dynamic damper without affecting the operability of the horn switch
