PURPOSE: A vaporizer for an LPG(Liquefied Petroleum Gas) vehicle is provided to precisely control the amount of the fuel flowing into a secondary pressure chamber through the space between a secondary valve and a secondary valve seat by maintaining the uniform placing point between a diaphragm rod and a secondary valve rod. CONSTITUTION: A diaphragm guide member(36) installed in a secondary pressure chamber keeps the placing point between a diaphragm rod(28) of a secondary diaphragm(24) and a secondary valve rod(30). Herein, the upper end of the diaphragm guide member is fixed on an upper wall portion of the secondary pressure chamber, while the lower portion is expanded toward the upper face of the secondary diaphragm and combined to a lower end cover(32). Thus, the diaphragm guide member prevents the uneven expansion of the secondary diaphragm.
