ABSTRACT:
When there is a difference in characteristic between sensing devices received respectively in receiving portions disposed at the opposite ends of a shackle pin and, therefore, the voltage of a load signal obtained from the sensing device in the receiving portion side is higher than the voltage of a load signal obtained from the sensing device in the receiving portion side because of the above-mentioned difference even if the loads imposed on the receiving portions respectively are equal to each other, configuration is made so that a correction resistor is parallelly connected to a detection winding of the sensing device in the receiving portion side. Accordingly, a part of the induced current flowing between opposite ends of the detection winding also flow in the correction resistor, so that a voltage drop occurs in the correction resistor. By this voltage drop, the voltage of the load signal obtained from the sensing device in the receiving portion side is made coincident with the voltage of the load signal obtained from the sensing device in the receiving portion side.
