While attaching the magnetic body that has it, to the body side fixing member that does not rotate,
There is a proximity switch in which a coil is wound around a magnetized iron core so as to face the outside of the magnetic body. The rotation of the wheel causes the uneven portion of the magnetic material to rotate in front of the proximity switch, which causes a voltage to be generated by electromagnetic induction in the coil each time the protrusion passes, and the rotation speed of the wheel is detected at the cycle of this induction voltage. ing.
