TWIST MOVEMENT DEVICE

To provide a twist movement device that uses a common compression spring used widely, and thereby can simply be used by a simple structure.SOLUTION: A twist movement device concerning the present invention is provided as follows: a left slider, left screwdriver, bearing and left grip, and a right slider, right screwdriver, bearing and right grip are arranged, by equalizing an axis line, respectively, toward the outside of both ends across a cylindrical compression spring on a circumference of a columnar core guide; The left or right grip are integrally connected with the left or right screwdriver, respectively; the screwdriver is screwed with the slider; the twist movement is made by gripping the left and right grip, respectively; then, the compression spring is configured so that the left and right sliders are made to advance in an opposite direction and are pressed by the rotation around the axis line of the left and right screwdrivers; and the reaction force acting on the left and right screwdrivers by the compression spring is supported by the bearing.SELECTED DRAWING: Figure 1 【課題】広く使用されている一般的な圧縮バネを使用し簡単な構造で簡易に使用することができるねじり運動具を提供する。【解決手段】本発明に係るねじり運動具は、円柱状の芯ガイドの周上に、筒状の圧縮ばねを挟んでその両端外方に向けそれぞれ軸線を同一にして左スライダ、左ドライバ、軸受及び左グリップと、右スライダ、右ドライバ、軸受及び右グリップが配設され、前記左又は右のグリップはそれぞれ前記左又は右のドライバと一体に連結され、前記ドライバとスライダはねじ係合しており、前記左右のグリップをそれぞれ把持してねじり運動をすると、前記圧縮ばねは、前記左右のドライバの前記軸線回りの回転により前記左右のスライダが対向方向に前進して押圧されるとともに、前記圧縮ばねにより左右のドライバに作用する反力が前記軸受により支えられるようになっている。【選択図】図１
