Position determination device for movable components of vehicle e.g. motorcycle, has magnetic field screening flag units set between magnetic bodies and Hall units in rotor body for moving into recess

摘要

A position sensor switch (2(3)) has a stator body (28) and a rotor body (29) respectively provided to the vehicle components. The Hall units (25) are arranged opposite with the magnetic bodies (23) in the stator body. The rotor body is provided with magnetic field screening flag units ((22.1,22.2)22.3) between the magnetic bodies and Hall units that are movable to a recess (30) in a first sensor twill.
