Claims

[Scope of utility model registration request]

A pole piece 3 around which a coil 5 is wound is arranged at the tip of a magnet 2, and an alternating current voltage is excited in the coil 5 as a magnetic rotor rotates, which is brought close to the tip of the pole piece 3. A rotation sensor that outputs a rotation sensor, characterized in that a pole tip member (10 or 13) is detachably attached to the tip of the pole piece 3.
