PURPOSE:To provide a grease filter with the filter medium fixed to a frame surely and firmly, with the filter medium easily attached or detached. CONSTITUTION:This grease filter is formed by clamping a filter medium 3 between the outer frame 1 and inner frame 2 made of stainless steel. First detaining pieces 6A and 6B are arranged to the peripheral edge 1A of the outer frame 1 on the upper side when set, and second detaining pieces 7A and 7B are furnished on the lower side. The protruding length of the first detaining pieces 6A and 6B are made larger than that of the second detaining pieces 7A and 7B. Meanwhile, plate springs 8A and 8B are fixed to the inner face of the peripheral edge 1A of the outer frame 1, and the inner frame 2 is inserted in the same way in which a window is set. A coil spring and other elastic members of heat-resistant rubber, etc., can be used instead of the plate spring, and an elastic member can be fixed on the inner frame side. Further, the outer frame and inner frame can be integrated, and one or both of the frames can be split. |
