【考案が解決しようとする課題】[Problem that the idea aims to solve]

このため、中立状態にある操作レバ−が、バネ反力や車体振動、操作レバ−の 質量等によって不測に振れ易く、また、不意に操作レバ−から手を放した時にも 操作レバ−が不測に振れ、操作レバ−の不測の振れによって予期しない時に被動 部が作動するという問題が生じる。 そこで、操作レバ−の不測の振れを無くするために、被動部のリタ−ンスプリ ングのバネ力を強くする、或いは操作レバ−を中立位置に保持するための戻しバ ネを、操作コラムと操作レバ−との間に張装付加することなどが考えられるので あるが、何れにしても操作レバ−の操作荷重が増大されてしまうので操作性が悪 化する上、被動部全体が大型になったり操作レバ−の構造が複雑になるといった 別の問題を生じることになる。 For this reason, the control lever in the neutral state may be affected by spring reaction force, vehicle body vibration, or It is easy to shake unexpectedly due to its mass, and even when you release the control lever unexpectedly. The control lever swings unexpectedly, and the control lever swings unexpectedly. The problem arises that the section operates. Therefore, in order to eliminate unexpected vibration of the operating lever, the return spring of the driven part is A return bar is used to strengthen the spring force of the operating lever or to maintain the operating lever in the neutral position. It is possible to add tension between the operation column and the operation lever. However, in either case, the operating load on the operating lever increases, resulting in poor operability. In addition, the entire driven part becomes larger and the structure of the operating lever becomes more complicated. This will cause another problem.
