PURPOSE: A filter cover of a solenoid valve for an LPG(Liquefied Petroleum Gas) vehicle is provided to cut down manufacturing cost by integrally forming the filter cover through injection-molding plastic and increasing the gap of the guide in the outer periphery, and to replace the filter timely by checking pollution level with the unaided eye. CONSTITUTION: A filter cover(10) is formed by integrally forming a filter guide part(10a) with an outer wall, and manufactured by injection-molding plastic. The filter guide part supports the upper part and the lower part of a filter(11), and the outer wall surrounds the circumference. The outer wall of the filter cover is exposed with the latticed structure of 5*7 mm to look in the wall. The filter guide part and a filter installation part(10b) are integrally formed in inserting the filter in injection molding. The upper part of the filter is surrounded by the filter guide part, and the lower part of the filter is finished by the filter installation part.
