Claim 7:
8. The tactile presentation device according to claim 4,
wherein the vibration generator includes a first internal 5 vibrator and a second internal vibrator disposed at a position facing the first supporting member across the target area,
wherein the first internal vibrator is disposed between the second internal vibrator and the target area,
wherein the drive control device selects a standing wave that makes vibration of the vibration generator closest to a reference frequency, among a plurality of standing waves having a node at the touch position at which tactile feedback is not presented, and
wherein, at the reference frequency, the carrier wave from the first internal vibrator and a reflected wave at the second end of the second internal vibrator strengthen each other between the vibration generator and the first end.
