Abstract: PURPOSE: A non-contact type rotational sensor is provided to obtain the change of a magnetic field as the rotation of a magnet and a rotational angle by using a hall IC(integrated circuit) and the magnet. CONSTITUTION: A hall IC(50) is fixed on a printed circuit board(40) and a magnet(34) is installed on a shaft at a specific interval with the hall IC. The shaft(32) is rotated by a rotational body so that the magnet is rotated. A change of a magnetic field is generated on a side face of the magnet. Otherwise, the hall IC is fixed on the printed circuit board and two magnets are accepted in the shaft within a cover at a specific interval with the hall IC. The shaft contacts a rotor and the hall IC is positioned in a groove formed on the cover. A spring is installed on an end of the shaft. Due to the linear movement of the shaft, the change of the magnetic field occurs on an inner face of the magnet. Then, the rotational angle is measured in the hall IC.
