Abstract

PURPOSE:To make the turning force conformed to the manipulated variable of a steering lever securable by detecting each rotational frequency at both driving and driven shaft sides of a friction coupling, and making the ratio of both sides during turning motion so as to become such a value that corresponds to the manipulated variable of the steering lever. CONSTITUTION:When a steering lever 25a is operated, a driving duty ratio D of the solenoid SOL1 conformed to the output value of a volume VR1 is read out of a read-only memory 32. When a clutch part alone operates at a steering gear, a duty ratio of the solenoid SOL1 is altered so as to cause a ratio Ra between speed sensors S1 and S3 to accord with a transfer ratio R being prestored in the ROM 32. When operating levers 25a and 25b are operated and each output of volumes VR1 and VR2 comes to the specified output, directional control valves 21a and 21b comes into a state of being situated in a position P2 or P4, thus a braking part operates.
