To realize a circuit controller for a new electric point machine which prevents the intrusion of organisms such as ants and suppresses the abrasion or dust generated by the swinging of a lever as much as possible while securing a space where the lever is swung.SOLUTION: In a circuit controller 2 for an electric point machine, a shaft support base 50 rotatably supports a swing shaft 30 of a lever 22 while the swing shaft is suspended. A closing member 60 is mounted on the periphery of a lower end part of the swing shaft 30 mounted with the lever 22. The closing member 60 separates an in-device space from the outside of the device so as to prevent intrusion of organisms. The closing member 60 defines a swing space 90 in which lower end parts of the lever 22 and the swing shaft 30 can be arranged such that the lever 22 can swing inside of the in-device space. In the swing space 90, the lever 22 and the swing shaft 30 are supported so as not to be contacted with a floor surface of the swing space 90 by the support of the swing shaft 30 by the shaft support base 50.SELECTED DRAWING: Figure 3
【課題】レバーが揺動する空間を確保しつつ、蟻等の生物侵入を防止し、レバーの揺動に伴う摩耗や粉塵の発生をできる限り抑制する新たな電気転てつ機用の回路制御器を実現すること。【解決手段】電気転てつ機用の回路制御器2は、軸支持台50で、レバー22の揺動軸30を吊り下げた姿勢で回転自在に支持する。レバー22が取り付けられた揺動軸30の下端部の周囲には閉塞部材60が装着され、閉塞部材60が生物侵入を阻止するように器外と器内空間とを隔てる。閉塞部材60はその内部に、レバー22が揺動可能な状態でレバー22および揺動軸30の下端部を配置可能な揺動空間90を画成する。揺動空間90内では、軸支持台50による揺動軸30の支持によって、レバー22および揺動軸30が揺動空間90の床面に非接触な状態で支持されている。【選択図】図3
