針式計器の零復帰装置。 In a meter that measures the amount of change in the object to be measured by displaying the pointer on a scale plate by rotating the pointer shaft with a pointer fixed to one end, the pointer shaft is The pointer is returned to zero via the magnetic plate by means of a magnetic plate orbiting around the magnetic plate and a magnetic field application means disposed close to and opposite to the magnetic plate, and the shape of the magnetic plate is changed in stages to the zero return attraction force. A zero return device for a pointer-type meter, characterized in that it has a shape that allows it to.
