LEVER DEVICE FOR FORCE FEEDBACK OPERATION

摘要

PROBLEM TO BE SOLVED: To provide a technology for flexibly feeding back the state of a working machine as represented by discontinuous operations of an actuator, as a sense of force to an operator. SOLUTION: The lever device 100 for force feedback operation includes: an operation lever 1; an operation lever support 2 for supporting the operation lever 1 so as to be tiltable; an electromagnetic means (DC brushless motor 3 or the like) for generating electromagnetic torque as a reaction force to the tilt of the operation lever 1; a frictional brake mechanism 7 (frictional brake means) generating frictional torque as a reaction force to the tilt of the operation lever 1; and a control means 50 for controlling the operation of the electromagnetic means and the frictional brake mechanism 7 so that the electromagnetic means and the frictional brake mechanism 7 generate torque as a reaction force to the tilt of the operation lever 1 in a mutually complementary manner.
