Input device

An input device comprising:

• a touch input part installed on a steering wheel of a vehicle and supported so as to be able to vibrate;
• a detection part configured to detect an input operation to the touch input part;
• a vibration output part configured to vibrate the touch input part;
• and
• a controller configured to drive the vibration output part, wherein:
• when the input operation is detected by the detection part, the controller is configured to cause vibration of the touch input part by driving the vibration output part with a first signal;
• a vibration transmission member is provided on a vibration transmission path from the touch input part to the steering wheel;
• and
• the first signal is configured to drive the vibration output part at a frequency in a vibration damping region where a resonance multiplying factor of a vibration system provided on the vibration transmission path is less than zero.
