PURPOSE:To finely adjust the speed of a motor-driven vehicle by setting the operating range of forward and reverse movements of a joy-stick lever to a larger value than that of right and left spins. CONSTITUTION:A joy-stick lever 5 is inserted into the long holes 1C, 2C at the centers of a swinging arm 1, 2. The tiling operation of the lever 5 is converted to a rotating motion at pivots 1A, 1B and 2A, 2B as rotating pivot on the central axes 01, 02 of the arms 1, 2, the rotating displacement is transmitted to a command variable resistor as it is, and output as change in an electric resistance value. Further, in case of operating the lever 5, the operating range of forward and reverse movements of a motor-driven vehicle to be set in advance in set to a larger value than that of right and left spins. Thus, the forward and reverse operations of the vehicle can be more finely conducted to remarkably improve the operability of the vehicle. |
