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
