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
