Abstract
A force-sense-imparting operation device including a stationary section, a rotating section, and an operation member. One of the stationary section and the rotating section includes an excitation coil and a first magnetic pole section, and the other includes a second magnetic pole section capable of opposition to the first magnetic pole section in a specific opposing direction. The first magnetic pole section forms a magnetic circuit with the first magnetic pole section due to the second magnetic pole section being excited in a state that the second magnetic pole section opposes the first magnetic pole section. The magnetic circuit encircles a periphery of the excitation coil on the cross section, the second magnetic pole section being arranged to separate from the first magnetic pole section with rotation of the rotating section.
