Claims

[Claims for Utility Model Registration] A cross coil is constructed by winding two coils around a coil bobbin in directions orthogonal to each other, and a magnetic rotor is placed inside the cross coil, centered around a rotating shaft with a pointer fixed to the tip. A hairspring with one end of a return hairspring fixed by solder is press-fitted and fixed to the rotating shaft so as to be freely rotatable.
In a cross-coil type indicator that drives the magnetic rotor to rotate by a predetermined angle in response to a composite magnetic field of magnetic fields generated by the coils when the coils are energized, 1. A cross-coil type indicator, characterized in that a tapered part is formed at the tip of the shaft, and a slit is formed at a position corresponding to the tapered part of the bead.
