To generate vibration easily felt by an operator.SOLUTION: A steering wheel includes an annular rim, a vibration mechanism provided within the rim, and a vibration control unit configured to control the vibration mechanism. The vibration mechanism includes at least one piezoelectric element configured to vibrate in accordance with an electric voltage applied by the vibration control unit, and an amplification mechanism configured to amplify vibration of the piezoelectric element. The amplification mechanism vibrates with an amplitude greater than that of the piezoelectric element and thereby vibrates the rim. A vibration device for a steering wheel includes a vibration mechanism and a vibration control unit configured to control the vibration mechanism. The vibration mechanism includes at least one piezoelectric element configured to vibrate in accordance with an electric voltage applied by the vibration control unit, and an amplification mechanism configured to amplify vibration of the piezoelectric element. The amplification mechanism vibrates with an amplitude greater than that of the piezoelectric element and thereby vibrates the rim of the steering wheel.SELECTED DRAWING: Figure 3

    【課題】運転者が感じやすい振動を発生させること。【解決手段】環状のリムと、前記リムに内蔵される振動機構と、前記振動機構を制御する振動制御部とを備え、前記振動機構は、前記振動制御部によって印加される電圧に応じて振動する少なくとも一つの圧電素子と、前記圧電素子の振動を増幅する増幅機構とを有し、前記増幅機構は、前記圧電素子の振動よりも大きな振幅で振動することにより前記リムを振動させる、ステアリングホイール。ステアリングホイール用の振動装置であって、振動機構と、前記振動機構を制御する振動制御部とを備え、前記振動機構は、前記振動制御部によって印加される電圧に応じて振動する少なくとも一つの圧電素子と、前記圧電素子の振動を増幅する増幅機構とを有し、前記増幅機構は、前記圧電素子の振動よりも大きな振幅で振動することにより、ステアリングホイールのリムを振動させる、振動装置。【選択図】図3
