PURPOSE: A pressure reducer of an LPG(Liquefied Petroleum Gas) vehicle is provided to improve the commercial value and safety of a vehicle by surely cutting off the supply of fuel when an engine is restarted and by avoiding the delay of hot or cold starting. CONSTITUTION: A pressure reducer(100) of an LPG vehicle is divided into a first pressure reducing chamber and a second pressure reducing chamber(120). The first pressure reducing chamber includes a first valve, a first valve lever, a first diaphragm and a first diaphragm spring. The second pressure reducing chamber includes a second valve(122), a second valve lever(124), a second diaphragm(126) and a second diaphragm spring(128). A fuel cut solenoid(140) is installed on a connecting path(101) between the first pressure reducing chamber and the second pressure reducing chamber. The fuel cut solenoid surely cuts the inflow of fuel to the second pressure reducing chamber. Therefore, defective starting due to enriching or leaning of fuel is avoided.
