PROBLEM TO BE SOLVED: To provide a processing jig that prevents dislocation of a round seat and creasing of a decorative sheet, when a lever handle is operated.SOLUTION: A processing jig has a circular arc-form groove 21 formed on an end thereof. A plurality of reference rods 18 is planted on a surface of the processing jig in a set development pattern. Furthermore, a plate-form reference rod having a knob 19 protruded is planted on the other surface of the processing jig, the plate-form reference rod being exposed from a prepared hole 14 opening on a door surface and inserted into each of a plurality of fitting and insertion holes 11 on a column that opens in the same development pattern, thereby setting a relative position between the groove 21 and a round seat at a prescribed positional relationship. Then, a cutter is inserted into the groove 21 for cutting a decorative sheet along the groove, thus cutting out the decorative sheet in a circular form having a same diameter as an outer diameter of the round seat.SELECTED DRAWING: Figure 4 |
