A steering angle sensing device for vehicle wheel alignment includes a swingable rocking arm. The rocking arm can be located in a predetermined position and slidably connected with a simple wheel alignment calibrator. When a wheel of the vehicle is steered, the wheel alignment calibrator affixed to the wheel is synchronously rotated along with the steering of the wheel. At this time, the rocking arm is driven to swing by a corresponding angle and the steering angle sensing device emits a human-perceivable signal to a calibration worker, whereby the calibration worker can real-time know the steering angle of the wheel for conveniently performing the wheel alignment process.
