ABSTRACT:
A cross coil-shaped indicating instrument includes a cross coil structure in which two coils are wound around a coil bobbin at right angles to each other. The coil structure is electrically charged in correspondence to the amount measured so as to form a composite magnet. A magnet rotor is disposed inside the cross coil structure. The magnet rotor has a center rotary shaft rotatable at a predetermined angle in correspondence to the composite magnetic field. A pointer is fixed to the end of the rotary shaft. In order to press the pointer into an appropriate position with respect to the rotary shaft, a pressure recess is formed in the coil bobbin so that a rod-like fixture can be inserted into the recess, and a stopper projects inside the pressure recess to press against the magnet rotor when the fixture is inserted. The stopper makes the magnet rotor stationary. While the rotary shaft remains stationary, the pointer can be fixed to an predetermined indicating position.
