<p>PROBLEM TO BE SOLVED: To provide an inner force sense presenting device which is small-sized, lightweight, and inexpensive, hardly gets out of order, and never damages a user owing to a runaway. SOLUTION: This device consists of a shell member 2 formed of a flexible material, a tube 6 which is incorporated in the shell member and filled with a magnetic liquid 5, and a control means 9 which controls the flow of the magnetic liquid depending upon the movement of a body in the shell member. The fluid resistance of the magnetic liquid is varied by applying a magnetic field thereto to generates a desired reaction force and a means which applies the magnetic field to the magnetic liquid can be constituted so as to be small sized and light weight.</p> |
