Claims (1)
支軸にブツシユを介して操作レバーのボスを軸支
した操作レバー装置において、操作レバーのボス
両側周面に溝を設け、該溝にそれぞれＯリングを
嵌合し、中央部のＯリングの緊縛力を両端部のＯ
リングの緊縛力よりも強くしたことを特徴とする
操作リンケージのシール構造。 In an operating lever device in which a pivot shaft is fitted into a stay of a mounting frame and a boss of an operating lever is pivotally supported on the pivot shaft via a bush, grooves are provided on the circumferential surfaces of both sides of the boss of the operating lever, and grooves are provided in the respective grooves. Fit the O-rings and apply the binding force of the central O-ring to the O-rings at both ends.
The seal structure of the operating linkage is characterized by having stronger binding force than the ring.
