PROBLEM TO BE SOLVED: To prevent a potentiometer from detecting a backlash quantity generated in an interlocking part, as an actual operation quantity of an electric type actuator in error by providing an elastic flexible mechanism between a continuously variable transmission and a potentiometer in an interlocking mechanism. SOLUTION: An interlocking mechanism 10 is provided with an operation rod 10A connected to a belt type continuously variable transmission 6 and a rotary type potentiometer 14 which detects an actual operation quantity of an electric cylinder 11 on the basis of an oscillating seconds of arc of a bell crank 10B connected to the electric cylinder 11, and the detected actual operation quantity of the electric cylinder 11 is outputted to a controller 13. In addition, an elastic flexible mechanism 15 is arranged between the belt type continuously variable transmission 6 and the potentiometer 14 in the interlocking device 10, and a backlash generated because of vibration of an engine 5 and the like is absorbed, so that the potentiometer 14 is prevented from detecting the backlash quantity generated between the continuously variable transmission 6 and the potentiometer 14 as the actual operation quantity of the electric cylinder 11 in error. In this way, high precise feedback control can be carried out. |
