摘要： A manipulation device has a manipulation body rotationally operated by the manipulator, a support body rotatably supporting the manipulation body, and a rotational load imparting mechanism. The rotational load imparting mechanism has a movable member engaged with the rotational axis of the manipulation body, a magnetism generating mechanism facing the movable member with a gap intervening, and a magnetic viscous fluid, its viscosity changing according to the strength of a magnetic field. The magnetism generating mechanism has a coil generating a magnetic field and a first yoke provided so as to enclose the coil. The first yoke has a first opposing part and second opposing part, which are separated by slits, on a side facing the movable member. The magnetic viscous fluid is filled in the gap, which is between the first opposing part and the movable member and between the second opposing part and the movable member.

摘要： A rotating body is rotatably supported on a holding section. The holding section includes a rotation detection unit, a torque-applying unit, and a brake-applying unit. The torque-applying unit includes an A-phase torque-applying coil and a B-phase torque-applying coil, and a resistance torque and a pull-in torque applied to a rotor (magnet) are caused to vary as a result of controlling supply of current to each of the coils. In addition, a braking force can be controlled by supplying current to a brake-applying coil included in the brake-applying unit.

摘要： A torque generation apparatus includes a magnetic disc rotatable about a rotation axis, a first yoke, a second yoke, a magnetic viscous fluid placed between the magnetic disc and the first yoke and the second yoke, a coil, and a third yoke. The coil overlaps with the magnetic disc as viewed along the rotation axis. The third yoke constitutes a magnetic path of a magnetic field generated by the coil together with the first yoke and the second yoke. The magnetic disc includes a torque increasing portion at at least one of a surface facing the first yoke and a surface facing the second yoke. The torque increasing portion is provided in an outer circumferential area of the magnetic disc in a radial direction and causes a shearing force to a cluster of the magnetic viscous fluid to become larger than that in the inner circumferential area.
