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

Vibration reducing structure for steering wheel

A vehicle body structure in which a hollow-section crossmember is attached to rear end portions of right and left center frame members is provided. Right and left extension members extending rearward are joined to the rear end portions of the right and left center frame members. The crossmember is joined to the tops of the right and left extension members. Right and left reinforcing plates are provided in a hollow space of the crossmember at portions at which the extension members are joined to the crossmember. The right and left reinforcing plates are supported on the right and left extension members, whereby the crossmember is firmly supported on the rear end portions of the center frame members and is increased in rigidity.
