PURPOSE:To make the handling of transmission at the turning simply and easily, by furnishing a manual lever linking arm operating freely, as well as fixing a foot pedal linking arm to a transmission shaft of a hydraulic continuously variable transmission, and connecting the both arms through pins and twisting spring holding members. CONSTITUTION:To a transmission case 9 on a machine board 8 on which an engine is loaded, a hydraulic continuously variable transmission 1 is furnished to carry out the continuously variable transmission hydraulically, and to its transmission driving shaft 2, an operation shaft 11 is installed with pins, and a pedal linking arm 14 linking to a foot pedal is fixed. A lever linking arm 15 linking to a manual lever through a friction plate 31 and the like is inserted to the operation shaft 11 rotatable freely. At the ends of the both arms 14 and 15, pins 12 and 17 are arranged, and the both pins are connected with twisting spring holders 18. The vehicle runs by the transmission with the manual lever in a normal running, the speed is decelerated by the operation of the foot pedal in a turning, and the transmission is restored to the original position by releasing the foot pedal after the turning is over. In such a way, the handling can be made simply and easily.
