PURPOSE:To omit the adjustment of centering after operation by forming a locking means of an operating lever and a detent means of a fork shaft and coupling an I/O side member of a fork shaft driver with an adjustable connecting mechanism. CONSTITUTION:The operating lever 1 coupled with a push-pull cable 3 is locked at a neutral position by the locking means 9 and the fork shaft working device 2 is coupled with the connecting mechanism 2a by the detent means 4a by regarding the course of a shaft 21 from the fork shaft 4 as the neutral position. A fitting error from the operating lever 1 to an arm 22 and a fitting error from the fork shaft 4 to the shaft 21 are integrated to the arm 22 and the shaft 21 of the working device 2, but the errors are absorbed by selecting a fitting angle by the connecting mechanism 2a. The coupling of the connecting mechanism 2a which is executed at the final stage of an assembling process can be also applied to the centering adjustment of the whole operating system, so that a specific adjusting process can be omitted. |
