Braking torque based on a friction force is increased in a pulse state in a transition area in which control torque changes from a direction to encourage the rotation of a manipulation member to a direction to suppress the rotation. This braking torque based on a friction force does not cause vibration unlike the driving torque of an electric motor even if the braking torque is steeply increased. Therefore, when the rotational angle passes through the transition area, a clearer click feeling can be generated without a change like vibration being caused in control torque. When the manipulation member is rotated fast, the braking torque in a pulse state is likely to be felt as vibration.
