Abstract
A parking brake releasing mechanism for used in a vehicle which has solved an apparently illogical problem, that is, minimizing the operating power of the brake releasing rod (or lever in some case) without increasing the stroke thereof, by ingeniously combining a first lever secured to a pawl for restraining the quadrant or toothed portion and a second lever operated by a brake releasing rod, in their constructing way such that the lever ratio is maintained large while the pawl is in engagement with the quadrant and is lowered after the engagement has been released.
