Haptic feedback input device

A haptic feedback input device (5) includes a power supply unit (7) that supplies a torque of a motor to an operating part (6); a movable part that operates with the rotation of the operating part (6); a control unit (60) that calculates the rotational speed of the operating part from the change in the rotational angle detected by a rotary encoder (18) and controls the motor according to the rotational speed in order to control a resistance force applied to the operating part according to the rotational speed of the operating part (6); a movable part fixed to the operating (6) part to rotate with the operating part (6); a front cover that is mounted at the front of the power supply unit (7) and has a cylindrical portion which comes into sliding contact with a cylindrical portion of the movable part; and grease filled between the cylindrical portion and a cylindrical portion to generate a viscous resistance against the movable part.
