  • Patent number: 10557533
    Abstract: A linear motion mechanism with precise linear motion has structural robustness and allows easy reduction in weight and size, simple production and easy operation. The linear motion mechanism includes: an elastic arrangement which is arranged to transform an input direction and an input displacement to an output direction and an output displacement, wherein the output direction is orthogonal to the input direction; an operating member which is arranged to deform the elastic arrangement in the input direction by the input displacement; and a movable member fixed to the elastic arrangement to move in the output direction by the output displacement.
