摘要:
To provide a tactile vibration applying device that efficiently outputs vibrations using an electrostatic or piezoelectric actuator. The tactile vibration applying device includes the electrostatic or piezoelectric actuator formed in a flat shape, and expanding and contracting in a thickness direction, a first elastic body having an elastic modulus smaller than an elastic modulus of the actuator in the thickness direction and disposed to contact a surface of the actuator on a side of the first electrode, and a first cover covering a surface of the first elastic body opposite to a surface of the first elastic body contacting the actuator, pressing the actuator and the first elastic body in the thickness direction of the actuator, and holding the first elastic body in a state that the first elastic body is compressed more than the actuator.
