A hose that communicates the pressure chambers formed at both ends with the pressure chambers of the two master cylinders and the shift rail, respectively, and supplies the pressure oil of the master cylinder generated by the operation of the shift lever to the pressure chamber of the shift rail. A forklift gearshift operating device characterized by: (2) A claim in which pressure chambers formed at both ends of a shift rail are constructed by an operation cylinder mounted on a transmission case, and a piston in the operation cylinder and both ends of the shift rail are connected by push rods.
(1) The forklift gear shift operation device described in (1). (3) One double-acting master cylinder that gives reciprocating motion to the internal piston when the shift lever is operated, and the internal cylinder that is attached to the outside of the bearing part of the transmission case that slidably supports the shift rail. One double-acting operation cylinder having a piston connected to the end of the shift rail communicates each pressure chamber of the double-acting master cylinder with each pressure chamber of the double-acting operation cylinder to operate the shift lever. A speed change operation device for a forklift, comprising a hose for feeding pressure oil generated by a master cylinder to an operation cylinder.
