PROBLEM TO BE SOLVED: To suppress vibrations of a steering wheel at a plurality of frequencies in a plurality of directions, with a simple construction.SOLUTION: A vibration damping structure of a steering wheel 12 functions an inflator 50 as a damper mass of a dynamic damper by supporting the inflator 50 by a supporting member 40 disposed in a front side of a vehicle via a damper rubber 55. The damper rubber 55 includes a damper body 56 which is cylindrical and arranged between a flange portion 52 of the inflator 50 and the supporting member 40 so that its center axis L2 extends in a front-to-rear direction. The damper rubber 55 also includes ribs 57 and 58 having an end face of one of the ribs in a direction along the central axis L2 as a base end surface 59, and protruding outwardly from a part of an outer circumferential surface 56A of the damper body 56 in a circumferential direction in a state where the base end surface 59 contacts or approaches the supporting member 40. |
