PURPOSE: A braking device prevents a vehicle from sliding when the vehicle starts on a steep road. CONSTITUTION: A braking device comprises a braking operation part(30), a brake pressure supplying part(40) and a brake pressure discharging part(50). The braking operation part(30) is installed on one side of a propeller shaft(12) to brake the propeller shaft(12) by the brake pressure of an air brake. The brake pressure supplying part(40) is formed between the braking operation part(30) and an air pipe(26) to unidirectionally supply air moving between a relay valve(22) and a brake chamber(24) of an air brake device to the braking operation part(30). The brake pressure discharging part(40) is formed by branching off from the brake pressure supplying part(40) to selectively release the brake pressure acting on the braking operation part(30) by the operation of a clutch pedal.
