To suppress the occurrence of abnormal noise.SOLUTION: A support member 31 for a steering wheel is inserted through a bag holder 21 of an air bag device, and a slider 32 is covered over the support member 31 so as to be slidable in a longitudinal direction. A damper holder 42 covers a part of an axial region of the slider 32, and an annular elastic member 41 is interposed between the slider 32 and the damper holder 42. The steering wheel causes the air bag device to function as a damper mass of a dynamic damper and causes the elastic member 41 to function as a spring of the dynamic damper. The elastic member 41 comprises an inner rib 41j and an outer rib 41k set on the radial inside and the radial outside and extending in a circumferential direction, and the slider 32 comprises a pin holder rib 32d extending to the radial outside in the longitudinal direction, and the damper holder 42 comprises a damper holder rib 42f extending to the radial inside in the longitudinal direction.SELECTED DRAWING: Figure 9
【課題】異音の発生を抑制する。【解決手段】ステアリングホイールの支持部材31は、エアバッグ装置のバッグホルダ21に挿通され、スライダ32は、支持部材31に前後方向へスライド可能に被せられる。ダンパホルダ42は、スライダ32の軸方向の領域の一部を覆い、弾性部材41は、スライダ32及びダンパホルダ42の間に介装された環状の弾性部材41を有する。ステアリングホイールは、エアバッグ装置をダイナミックダンパのダンパマスとして機能させ、かつ弾性部材41をダイナミックダンパのばねとして機能させている。弾性部材41は、内径側及び外径側に設定された周方向に延びる内リブ41jと外リブ41kを備え、スライダ32は、外径側に前後方向に延びるピンホルダリブ32dを備え、ダンパホルダ42は、内径側に前後方向に延びるダンパホルダリブ42fを備える。【選択図】図9
