Abstract: An improvement in the configuration of automobile steering wheel locking devices. The automobile steering wheel locking device pertaining to the present invention principally consists of components, which include a main body, stopping bar, lock, casing, hook, spring and holding shaft. A cross bar at the rear of the lock's turning piece rests on a groove at the front of the casing. Turning of the lock's turning piece causes the cross bar to push back the casing and compresses the spring, thereby releasing the hook quickly and allowing the locking device to be removed from the steering wheel. The locking device can be locked on quickly around the steering wheel by pushing the hook upward, thereby causing a grip slot on the inner side of the hook to grip onto an opening on the lower side of the casing. The locking operation is therefore automatic.
