イル形指示計器。[Claims for Utility Model Registration] Two coils are wound around a coil bobbin in directions orthogonal to each other to form a cross coil, and a magnet rotor is disposed inside the cross coil so as to be rotatable about its rotation axis. , an indicator needle is attached to the tip of the rotating shaft, and the magnet rotor is driven to rotate at a predetermined angle in response to a composite magnetic field of magnetic fields generated by the coils by energizing each coil, and the measurement quantity is determined by the indicator needle. In a cross-coil type indicator that displays, a zero return coil is arranged outside the coil and on the same line as the line connecting the north and south poles of the magnetic rotor, and when returning to zero, the zero return coil is energized. A cross-coil type indicating instrument characterized by being equipped with a drive circuit that causes the
