Abstract
A manipulation apparatus that generates a manipulation reaction force on a manipulation knob by energizing a coil disposed between a coil-side yoke and a magnet. A permanent magnet is disposed on a contact portion for a housing of a knob base on which the manipulation knob is mounted. An electromagnet is disposed on a support portion of the housing that supports the contact portion. The electromagnet is energized to generate a repulsive force between the support portion and the contact portion. This reduces a friction force exerted between the support portion and the contact portion.
