Zusammenfassung:	PROBLEM TO BE SOLVED: To improve detection accuracy of a rotation angle using a signal rotor. SOLUTION: A crank angle detector 11 is constituted of the signal rotor 12 fixed to a crankshaft 10, and a pickup coil 13 of an electromagnetic induction system. A plurality of tooth parts 14 are provided on the circumferential edge of the signal rotor 12. A guide recessed part 18 is provided between adjacent tooth parts 14, deeply in the radius direction of the signal rotor 12. A tooth bottom body 22 is stored slidably in the radius direction of the signal rotor 12 in the guide recessed part 18. A tensile spring 23 is interposed between the bottom wall surface 21 of the guide recessed part 18 and the tooth bottom body 22. The tensile spring 23 pulls the tooth bottom body 22 toward the bottom wall surface 21. COPYRIGHT: (C)2009,JPO&INPIT
