。[Claims for Utility Model Registration] (1) A disc-shaped rotating body that rotates in synchronization with the rotation of a multi-cylinder internal combustion engine and has an appropriate number of unit angle magnetic poles formed on its circumferential surface, and the rotating body A crank angle sensor comprising magneto-electric conversion means that is fixedly disposed near the unit angle magnetic poles and detects a unit angle for each crank angle as appropriate from changes in the magnetic field caused by the unit angle magnetic poles, the unit angle magnetic poles being formed continuously and at equal intervals. One row of magnetized strips is formed, and the magnetic flux densities of some of the continuous unit angle magnetic poles are made different to form cylinder magnetic poles indicating the cylinder position at a predetermined crank angle, and correspond to each cylinder of the internal combustion engine. A crank angle sensor characterized in that the number of magnetic poles having different magnetic flux densities is different, so that the predetermined crank angle position of each cylinder can be absolutely determined. (2) Claim 1 of the utility model registration claim is characterized in that the utility model is equipped with a plurality of the magnetoelectric conversion means, and is configured such that when one of the means fails, it is detected from the output of the remaining means. crank angle sensor.
