Abstract
A rudder angle sensor with high accuracy, including a memory for storing a correction value to correct a rotational delay of a driven gear relative to a main drive gear caused by a backlash at a time of reverse of a steering shaft, a computer for correcting the value measured by the measuring mechanism based on the correction value stored in the memory, to thereby, calculate the rotation angle of the steering shaft. The measured result of the driven gear obtained by the measuring mechanism is corrected based on the correction value, and therefore, the backlash existing between the main drive gear and the driven gear can be matched completely or approximately. Thus, the high accuracy angle sensor is realized.
