PROBLEM TO BE SOLVED: To provide a steering angle zero point correction device in which the setting precision of a steering angle zero point correction value can be raised.SOLUTION: A control device sets a yaw zero point correction value Yr_Z on the basis of a yaw rate sensor value Yr_R detected by a yaw rate sensor when a vehicle stops (the second timing t12). And, the control device calculates a steering angle zero point correction value _Z on the basis of a yaw rate calculation value Yr obtained by subtracting the yaw zero point correction value Yr_Z from the yaw rate sensor value Yr_R when the vehicle runs in a straight line after the vehicle starts (the fifth timing t15). After the fifth timing t15, the control device does not implement calculation of the steering angle zero point correction value _Z since it can be determined that the vehicle running condition changed from the initial condition of running.
