PROBLEM TO BE SOLVED: To prevent a feeling of strangeness in steering operation due to shaking without enhancing accuracy of a mechanism which generates steering reaction force and performing mechanical adjustment therefor.SOLUTION: A steering reaction force device 1 is configured to comprise: large gears 10 which rotate around a shaft together with first steering shafts 3 which rotate around a shaft accompanying rotation of steering wheels 2 around a shaft; first small gears 11 which engage with the larger gears 10 and provide rotation-driving force to the larger gears 10; first reaction force motors 13 which drive the first small gears 11; second small gears 12 which engage with the large gears 10 and provide rotation-driving force to the large gears 10; and second reaction force motors 14 which drive the second small gears 12. The first small gears 11 and the second small gears 12 are configured to together engage with one large gears 10 so as to be prevented from shaking, so that the necessities for enhancing accuracy in component design and assembly of the gears 10, 11 and 12 and mechanical adjustment therefor can be eliminated and also natural steering operation can be performed.SELECTED DRAWING: Figure 4

    【課題】操舵反力を発生させる機構の高精度化や機械的調整を行うことなく、ガタに起因するステアリング操作の違和感を防止すること。【解決手段】ステアリングホイール2の軸周りの回転に伴って軸周りに回転する第一操舵軸3と一体に軸周りに回転する大歯車10と、大歯車10に噛み合い、大歯車10に回転駆動力を与える第一小歯車11と、第一小歯車11を駆動する第一反力モータ13と、大歯車10に噛み合い、大歯車10に回転駆動力を与える第二小歯車12と、第二小歯車12を駆動する第二反力モータ14と、を備えた操舵反力装置1を構成する。一つの大歯車10に第一小歯車11と第二小歯車12がともに噛み合う構成とすることによって、そのガタを防止することができ、各歯車10、11、12の部品設計及びアセンブリの高精度化や、機械的調整が不要となるとともに、自然なステアリング操作を行うことができる。【選択図】図4
