PROBLEM TO BE SOLVED: To provide a reaction force output device which can suppress an excessive reaction force output during an operation.SOLUTION: In a reaction force output device which outputs force in an opposite direction to an operator, a drive part has a rotary output shaft. By driving a drive member connected to the output shaft, force in the opposite direction to the operation direction is output to the operator operated by a person. When the rotation of the output shaft does not exceed a threshold, a control part controls electric conduction to the drive part with a duty ratio based on an input value, whereas when the rotation of the output shaft exceeds the threshold, controls electric conduction to the drive part with a duty ratio based on the rotation of the output shaft.SELECTED DRAWING: Figure 1
【課題】操作中に過剰に反力が出力されるのを抑制することができる反力出力装置を提供すること。【解決手段】操作子に対して、操作とは逆向きの力を出力する反力出力装置において、駆動部は、回転する出力軸を有し、出力軸に連結された駆動部材を駆動することで、人により操作される操作子に対し、操作方向とは逆方向の力を出力し、制御部は、出力軸の回転量が閾値を超えない場合、入力値に基づくデューティ比で駆動部への通電を制御し、出力軸の回転量が閾値を超える場合、出力軸の回転量に基づくデューティ比で駆動部への通電を制御する。【選択図】図1
