ABSTRACT:
An automobile steering wheel lock comprising a recheted stick with a hooked end and a lock block with a stick hole to receive the stick therein and have itself slidable along the stick. The lock block comprises a pawl which is biased by a spring to engage the ratchet of the stick so that when the hook of stick is hooked on a spoke of a steering wheel, the lock block is movable toward the hooked end of stick to secure it on the steering wheel and not able to withdraw, owing to the engagement of the pawl with the ratchet. A de-engaging device is provided to release the engagement of the pawl with the ratchet so as to remove the lock off the steering wheel.
