A rotational angle detecting device includes a sensor portion disposed on a shaft. The sensor portion includes longitudinal hall elements disposed perpendicular to each other for outputting a hall voltage proportional to a magnetic flux induced by a magnet disposed on the shaft. The device also includes an engagement mechanism for maintaining a positional relationship with the magnet in which a center portion of the sensor is aligned with a center portion of the magnet.
