<p>PROBLEM TO BE SOLVED: To provide a filter fitting frame by which fine dimensional adjustment can be carried out accurately, rapidly, and easily for each site such as a range hood, and labor and time for fitting work of a filter can be reduced.SOLUTION: A filter fitting frame 1a includes: a filter frame 2a which is arranged along at least one side of a plate-like filter F having a required thickness and a rectangular shape in plane view, and has a single bottom-wide recessed groove 6 on one surface 4a of an extending piece 4 projected to an outside of the filter F; and a fitting frame 10a having a plurality of tip-spreading projections 12 fitting to the bottom-wide recessed groove 6 formed on a surface 11a facing the surface 4a of the filter frame 2a. A fitting position of the fitting frame 10a to the filter frame 2a can be selected at a plurality of places along a direction orthogonal to one side of the filter F by fitting the bottom-wide recessed groove 6 of the filter frame 2a and the tip-spreading projection 12 of the fitting frame 10a.</p> |
