Haptic feedback input device

摘要

There is disclosed a haptic feedback input device including a power supply unit that supplies a torque of a motor to an operating part; a movable part that operates with rotation of the operating part; a control unit that calculates the rotational speed of the operating part from the change in the rotational angle detected by a rotary encoder and controls the motor accordingly to control a resistance force applied to the operating part a movable part fixed to the operating part to rotate with the operating part; a front cover that is mounted at the front of the power supply unit and has a cylindrical portion which comes into sliding contact with a cylindrical portion of the movable part; and grease between the cylindrical portion and a cylindrical portion to generate a viscous resistance against the movable part.
