To provide a rotational load device capable of generating a rotational reaction force solely through mechanical components.SOLUTION: This rotational load device comprises: a rotary shaft 15 having, on its outer periphery, a cam groove 29, the axial position of which changes along the circumferential direction; an outer ring 16 having, on its inner periphery, an axial groove 28, extending in the axial direction; a steel ball 17 which comes into rolling contact with both the cam groove 29 and the axial groove 28; a cylindrical retainer 18 which holds the steel ball 17 in a retaining hole 30 formed to penetrate in the radial direction; and an elastic member 19 which biases the retainer 18 in the axial direction. The rotational load device applies a rotational reaction force to the rotary shaft 15 utilizing the elastic force transmitted from the elastic member 19 to the inner surface of the cam groove 29 through the retainer 18 and the steel ball 17.SELECTED DRAWING: Figure 2

    【課題】機械部品のみで回転反力を発生することが可能な回転負荷装置を提供する。【解決手段】周方向に沿って軸方向位置が変化するカム溝29を外周にもつ回転軸15と、軸方向に延びる軸方向溝28を内周にもつ外輪16と、カム溝29と軸方向溝28の両方に転がり接触する鋼球17と、径方向に貫通して形成された保持穴30で鋼球17を保持する筒状の保持器18と、保持器18を軸方向に付勢する弾性部材19とを有し、弾性部材19から保持器18と鋼球17とを介してカム溝29の内面に伝達する弾性力によって回転軸15に回転反力を付与する回転負荷装置。【選択図】図2
