Abstract
The present disclosure relates to a tactile presentation device that includes a tactile presentation knob placed on an operation screen and for presenting a tactile sense to a user via the tactile presentation knob. The tactile presentation knob includes a conductive elastic portion that includes a surface layer facing the operation screen and an inner layer located on the side opposite to the operation screen, and an operation part that fixes the conductive elastic portion. The surface layer is set to be subjected to greater shear deformation than the inner layer by an operation of the tactile presentation knob, to generate vibrations by a change in the frictional force, and to be subjected to greater compressive deformation than the inner layer by a press of the tactile presentation knob. The inner layer is set to have higher vibration transmissibility than the surface layer.
