Abstract: A vibration generating device includes a coil and a magnetic flux source. The magnetic flux source includes a left-hand magnet, a first middle magnet, a second middle magnet, and a right-hand magnet. The coil includes a left-hand coil and a right-hand coil. The left-hand coil and the right-hand coil each include a left-hand wire bundle and a right-hand wire bundle. Magnetic fluxes from the middle magnet passing through, in an up-and-down direction, a space between the right-hand wire bundle of the left-hand coil and the first middle magnet are less than magnetic fluxes from the left-hand magnet that pass through, in the up-and-down direction, a space between the left-hand wire bundle of the left-hand coil and the left-hand magnet.

Abstract: An operating device according to the present invention includes magnetic field generation means. The magnetic field generation means includes a coil generating a magnetic field when energized, and a yoke forming a magnetic path for the magnetic field passing through a rotor. A control unit includes magnetization means and rotational torque control means. The magnetization means supplies a current to energize the coil such that a residual magnetic field in the yoke is held at a predetermined magnitude. The rotational torque control means adjusts a current value applied to the coil in accordance with the magnitude of the residual magnetic field in the yoke. An absolute value of a maximum value of the current value applied to the coil by the rotational torque control means is smaller than an absolute value of a current value applied by the magnetization means.
