器の価格を引き下げるという大きな効果もあった。Further, according to the present invention, it is possible to provide a metal ball detector in which the constituent members can be integrated, the number of parts is small, and the manufacture and assembly are easy. In addition to the above effects, the position A between the magnetized portion and the object to be detected has a greater amount of change in the magnetic field depending on the presence or absence of the object to be detected than the position B on the extension line between the magnetized portion and the object to be detected. Since the size of the Hall sensor is large, the detection function can be improved by fixing the Hall sensor so as to be positioned between the magnetized portion and the object to be detected, even if the deviation in the performance of the Hall sensor due to the manufacturing capability of the Hall sensor becomes large. There was also a great effect that the Hall sensor, which was not damaged and resulted in high yield and low cost, could be used and the price of the metal ball detector could be reduced.
