PROBLEM TO BE SOLVED: To provide a whirl stop mechanism of a shaft which easily processes a housing, and can reduce a limit of a layout of the housing.SOLUTION: A whirl stop mechanism 10 of a shaft 1 for preventing the rotation of the shaft 1 by making the shaft 1 which integrally formed at a screw shaft 41 of a conversion device 4 related to this invention engaged with a housing 2 comprises a whirl stop part 13 which protrudes from an external peripheral face of the shaft 1 to the outside of a radial direction. A long hole 11 which is long in an axial direction of the shaft 1 is formed at the housing 2, and a fixing hole 12 which is recessed to the inside of the radial direction from the external peripheral face of the shaft 1, and opened toward the long hole 11 is formed at the shaft 1. The whirl stop part 13 has a fixed part 14 having an abutment part 17 which abuts on a pair of longitudinal faces 11a, 11a extending to an axial direction at an internal peripheral face of the long hole 11, and a fixing part 15 which penetrates the fixed part 14, is inserted into the fixing hole 12 at its one end, and fixes the fixed part 14 to the shaft 1.SELECTED DRAWING: Figure 2

    【課題】ハウジングの加工を容易とし、ハウジングのレイアウトの制限を低減できるシャフトの回り止め機構を提供することを目的とする。【解決手段】本発明に係る変換装置4のねじ軸41と一体に形成されたシャフト1とハウジング2を係合させてシャフト1の回転を防止するシャフト1の回り止め機構10であって、シャフト1の外周面から径方向外側に突出する回り止め部13を備え、ハウジング2には、シャフト1の軸方向に長い長孔11が形成され、シャフト1には、シャフト1の外周面から径方向内側に窪み、長孔11に向って開口する固定穴12が形成され、回り止め部13は、長孔11の内周面において軸方向に延在する一対の長手面11a,11aに当接する当接部17を有する被固定部14と、被固定部14を貫通するとともに一端部が固定穴12に挿入されて被固定部14をシャフト1に固定する固定部15と、を有することを特徴とする。【選択図】図2
