Vibration reducing structure for steering wheel

A vibration reducing structure for a steering wheel having a boss member and an airbag module arranged therein, said vibration reducing structure comprising

• a two-plate structure comprising a holder supported by the boss member;
• and a bracket supporting said airbag module;
• a plurality of floating support portions arranged on the holder;
• each of said floating support portions comprising
• a first elastic body supported on the holder;
• a slider supported by the first elastic body, said slider having an annular groove formed therein at an outer periphery thereof;
• and
• a second elastic body fitted in said groove of the slider;
• wherein
• said slider is movable in an axial direction thereof;
• said airbag module is supported inside the steering wheel via said plurality of floating support portions and the bracket such that said airbag module is movable in an axial direction of the steering wheel and in directions perpendicular to the axial direction;
• and wherein said second elastic body has a protrusion formed thereon, said protrusion protruding in an axial direction of the second elastic body such that said protrusion abuts a surface of said slider that is transverse to the axial direction.

A vibration reducing structure for a steering wheel, comprising

• a two-plate structure comprising a holder and a bracket, each having a contact point;
• a mass which is supported inside the steering wheel via an elastic body so as to be movable in a direction of an axis and a direction perpendicular to the axis, wherein a horn switch comprising the contact points of said holder and said bracket is activated by pressing the mass in the direction of the axis so as to establish contact between the contact points of said holder and said bracket and the mass is allowed to vibrate in the direction perpendicular to the axis to function as a dynamic damper, wherein
• the elastic body comprises a first elastic body and a second elastic body,
• a slider is supported on a fixed portion of the steering wheel and
• the mass is supported on the slider via the second elastic body and the bracket so as to be movable in the direction perpendicular to the axis,
• the slider is supported via the second elastic body, and
• a washer is disposed into a groove of the slider between the second elastic body and the slider;
• said second elastic body has a protrusion formed thereon, said protrusion protruding in an axial direction of the second elastic body such that said protrusion abuts said washer.
