Abstract: An airbag module that serves as a damper mass mounted to the steering wheel surrounding the center of steering of the steering wheel via vibration damping parts, the vehicle steering wheel structure damping steering wheel vibration, wherein the vibration damping parts includes at least a first vibration damping part positioned upward from the center of steering and a second vibration damping part positioned downward from the center of steering with reference to a neutral position of the steering wheel and the spring constant or elastic modulus of the first vibration damping part is set lower than the spring constant or elastic modulus of the second vibration damping part.

Abstract: This invention provides a vehicle steering wheel vibration reducing structure capable of effectively damping induced vibration generated in the steering wheel and contributing to vibration reduction in both low frequency bands and high frequency bands.
A vehicle steering wheel vibration reducing structure, where the vehicle steering wheel structure is such that an airbag module, which serves as a damper mass, is attached to the steering wheel via vibration damping parts to damp vibrations of the steering wheel, and where the airbag module is formed such that the upper region above the center of steering of the steering wheel is lighter than the lower region, with reference to a neutral position of the steering wheel.
