FORCE-SENSE-IMPARTING OPERATION DEVICE

摘要

This force-sense-imparting operation device is provided with a stationary section, a rotating section, and an operation member; one of either the stationary section or the rotating section has an excitation coil and a first magnetic pole section; the other of either the stationary section or the rotating section has a second magnetic pole section that can oppose the first magnetic pole section in a specific opposing direction; the excitation coil has an opposing site that opposes the second magnetic pole section; the first magnetic pole section has a shape that encircles the excitation coil excepting the opposing site in a cross section perpendicular to the direction of flow of excitation current in the excitation coil; the second magnetic pole section has a shape that forms a gap in the opposing direction between the first magnetic pole section and excitation coil and the second magnetic pole section when opposing the first magnetic pole section and forms a magnetic pathway that together with the first magnetic pole section, encircles the periphery of the first excitation coil in the aforementioned cross section by means of the second magnetic pole section being excited in the state of opposing the first magnetic pole section, and the second magnetic pole section is disposed in a manner so as to move away from the first magnetic pole section alongside the rotation of the rotation section.
