Tactile presentation device

A tactile presentation device comprising:

• a movable part that has a first main surface and presents tactile to a user by being displaced in a predetermined one axial direction parallel to the first main surface;
• a base that supports the movable part in a displaceable manner;
• a connector that connects the base to the movable part;
• and
• one or more actuators that displace the movable part in the one axial direction, wherein
• when the number of actuators is one, the actuator is located on a symmetry axis of the movable part parallel to the one axial direction,
• when the number of actuators is two and the two actuators have different outputs, the two actuators are disposed at positions, where a ratio of a vertical distance between one of the actuators and the symmetry axis to a vertical distance between a remaining one of the actuators and the symmetry axis is an inverse ratio of a ratio of output of one of the actuators to output of the remaining one of the actuators, with the symmetry axis interposed between the two actuators, and
• when the number of actuators is two or more and the two or more actuators have a same output, the plurality of the actuators is located symmetrically with respect to the symmetry axis.
