切換操作機構。 In a forklift operating device that has a torque drive transmission that moves a transmission valve spool using a shift lever and switches a forward/reverse clutch, the movement of the shift lever is transmitted to the piston via a rod to generate a hydraulic pressure difference within the cylinder. a double-acting master cylinder, a double-acting operation cylinder that operates a transmission valve spool via a rod by a piston installed outside an end of a transmission valve case and reciprocating inside; 1. A forward/reverse switching operation mechanism for a forklift operating device, comprising a pair of hoses that guide hydraulic pressure generated in the cylinder to the operation cylinder.
