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.
Claims8
A vehicle steering wheel vibration damping structure comprising:
- an airbag module that serves as a damper mass;
