Steering angle detection device
 A steering angle detection device of the type wherein a computer (12) calculates a steering angle. When a steering shaft (20) is turned, pulse signals (SS1, SS2) are generated from an encoder (10). In response to these pulses signals (SS1, SS2), the computer (12) detects the rotational direction and angle of the steering shaft (20). When a sampling signal is generated in relation to the running of a vehicle, the computer (12) calculates a mean value of a cumulative past rotational angles and further calculates the rotational angle of the steering shaft (20) relative to a neutral position indicated by the mean value.
