<p>PROBLEM TO BE SOLVED: To surely provide a structure for fixing a case and a cover by engaging a surely fitting protrusion with a fitting hole, even when the cover made of soft material is used. SOLUTION: A case 2 has a fitting protrusion 6 on a wall face 2a. A cover 5, assembled with the case 2 has a fitting member 8 that includes a fitting hole 7 which is engaged with the fitting protrusion 6. The cover 5 has a recessed part, in which a projected member 12 of a jig 9 is inserted, at a position near the fitting member 8. Then, the rigidity of the nearby part around the fitting member 8 in the cover 5 is enhanced. When the fitting protrusion 6 is fitted to the fitting hole 7 of the fitting member 8, the rigidity of the fitting member 8 and the nearby part of the cover 5 causes the fitting member 8 to move over beyond the fitting protrusion 6, so the fitting protrusion 6 is engaged with the fitting hole 7, and the case 2 and the cover 5 are fixed.</p> |
