PURPOSE:To simplify fitting work and to prevent a parmanent magnet from breakage or damage by providing the titled device with an output part consisting of a magnetic core and a coil and the parmanent magnet is put in and fixed on the inside of a cap with a bottom which is composed of a nonmagnetic material. CONSTITUTION:The rotation detector is provided with the output part 12 constituted by winding the coil around the magnetic core 10 consisting of iron or the like. The cap 16 formed by a cylindrical body composed of a nonmagnetic material puts in and fixes the parmanent magnet 17 on its inside with a filler or an adhesive 18. The parmanent magnet 17 put in and protected by the cap 16 is inserted by pressure and fixed into/on a fitting hole 20 formed on a prescribed position of a fly-wheel 15. Since the parmanent magnet 17 previously put in and fixed in/on the cap is attached to the fly-wheel, the fitting work is simplified and the parmanent magnet 17 is prevented from breakage or damage at the time of fitting. |
