- the method of detecting the movement of the rod 101 can be performed, for example, by detecting a change in electrical resistance using a variable resistor. 2 come. Alternatively, a method of detecting the movement width of the rod 101 as a change in magnetic resistance using a magnetic circuit is also possible. Also, as a method of detecting the operation width of the pedal 103, for example, a potentiometer 105 is attached to the rotation axis 102, and the rotation angle of the pedal 103 is detected by a change in electric resistance.

- the active reaction force separation unit 7 may be operated by a mechanical operation to prompt the active reaction force separation unit to be separated from the operation input unit.
- the operation input unit 1 is connected to the passive reaction unit 2 and the active reaction unit 3. Even when there is no reaction force from the active reaction unit 3, the passive reaction unit 2 generates a reaction force on the pedal. Therefore, even if the active reaction force section operates normally, the active reaction force section 3 is separated and the passive reaction force section 2 alone generates a reaction force on the pedal, thereby reducing power consumption. Can be suppressed. If the reaction force required by the pedal and the reaction force generated by the passive reaction force unit 2 are the same, the output of the active reaction force unit 3 is ideally set to 0.
