PURPOSE: A parking brake for a vehicle is provided to reduce lever ratio by separately dividing a position of a ratchet gear and to prevent breakage of a spring by preventing excess torque of a lock spring. CONSTITUTION: A parking brake of a vehicle comprises a spindle(20) mounted on a side portion of a parking lever(10); a first ratchet gear(30) fixed on the spindle; a gear unit(31) formed in the first ratchet gear; a second ratchet gear(40) contacted to the gear unit of the first ratchet gear; a lock spring(50) preventing reverse rotation by being arranged on a side portion of the second ratchet gear; an actuator(60) releasing the lock spring; an operational lever(70) connected to the lock spring; and a bracket(80) maintaining a shaft of the lock spring. The second ratchet gear is released by pushing an end portion of the lock spring while actuating the operational lever. Thereby, the parking brake of the vehicle reduces lever ratio by separately dividing a position of the ratchet gear. Moreover, the parking brake in the vehicle prevents breakage of the lock spring by preventing excess torque.
