PURPOSE:To confirm fitting with an object to be adjusted, to remove the influence of backlash, to prevent the object to the adjusted from damage, and to attain accurate and sure adjustment by providing the title device with a servo motor, a transmitting member, the 1st and 2nd detecting means, a motor driving circuit, and a control means. CONSTITUTION:An output of the servo motor 5 is transmitted to a bit 9 through the 1st and 2nd transmitting members 7, 8. Since the 1st transmitting member 7 can be moved in the axial direction and is excited in the left direction by a spring 10, the bit 9, the 2nd transmitting member 8 and a part 13 to be detected are moved in the right direction. A control circuit controls a current command value to a constant current amplifier by a Zener diode in a circuit connected by a remote switch 24, so that its output current is restricted and rotational torque >= a fixed value is restricted. On the other hand, the connected Zener diode is switched to another Zener diode having a different value to control the current command value and set up the limit value of the rotational torque. |
