<p>PROBLEM TO BE SOLVED: To solve the problem in which devices providing tactile sensations are late to get back to an original state from a shrinkage state.SOLUTION: The tactile sensation providing device comprises: an elastic body that expands on the basis of a pressing action and gets back to an initial state from an expansion state by a restitutive force; and a deformation device covered by the elastic body that, when a control is started on the basis of the pressing action, transits to a deformation state from a non-deformation state, and, when the control is ended, gets back to the non-deformation state. A time till the elastic body gets back to the initial state from the expansion state is shorter than a time till the deformation device gets back to the non-deformation state from the deformation state.</p> |
