To provide a mechanism that gives an optimal speed reduction ratio simply, in a device that manually and repeatedly applies force with a hydraulic jack or the like.SOLUTION: Applied force is input via a pair of fan-shaped gears having a gradient so that a gear ratio becomes smaller as a rotation angle becomes larger. Depending on the degree of inclination of a bar, the gradient causes gradually faster and weaker force in a selectable manner.SELECTED DRAWING: Figure 1
【課題】 油圧ジャッキなど手動で反復して加力する機器にて、簡便に最適な減速比を与える機構を提供する。【解決手段】 加えた力が、回転角が大きくなるとギア比が小さくなるように勾配を持たせてある扇型歯車の対を経由して、入力されるようにする。バーの倒し度合などにより、徐々に速く弱い力になる勾配になり、選択できる。【選択図】図1
