To provide an example basic structure of a bidirectional spring unit using a compression spring as a bidirectional spring according to a known technical concept, and to solve the problem that the bidirectional spring unit using the compression spring tends to have a double stroke to increase in overall length and the problem that a linear motion bearing part has a special structure using a guide of a spring and a geometric consideration thereby needs to be taken so as to obtain smooth motion.SOLUTION: A guide of a spring is called a spring piston (2), and outer diameters of two spring pistons (2) serving as a bearing of a cylinder holder (4) are made not cylindrical, but spherical so as to make motion with the cylinder holder (4) smooth. Shapes of necessary components are arranged axially inside the spring as much as possible.SELECTED DRAWING: Figure 1

    【課題】 公知の技術概念である双方向ばねで、圧縮ばねを使った双方向ばねユニットの基本構造の一例を提示することが、本発明の目的である。圧縮ばねを使った双方向ばねユニットはストロ−クが2倍になり全長が長くなる傾向がある。また、直動軸受部がばねのガイドを使った特殊な構造であるためスム−ズな動作を得るには幾何学的な配慮が必要である。【解決手段】 ばねのガイドをばねピストン(2)と呼び、シリンダホルダ−(4)の軸受となる2個のばねピストン(2)の外径を円筒ではなく球面状にすることで、シリンダホルダ−(4)との動作をスム−ズにした。必要な部品の形状を極力ばねの軸方向内側に配置した。【選択図】図1
