Summary:PROBLEM TO BE SOLVED: To make unnoticeable scratches or flaws on a resin case generated when a metallic shutter slides even when the resin case is formed of a transparent resin or soft resin, by providing a projection at a surface of the resin case for limiting a place where the metallic shutter slides. SOLUTION: A resin case 1 and a projection 4 are formed by injection molding in one body. The straight projection 4 is formed along a movable direction of a metallic shutter 2 at a face 3 of the metallic case where a lower part of the metallic shutter 2 slides. Therefore, a sliding place of the shutter 2 on the face 3 is limited to on a top of the projection 4. Since the generation of scratches or flaws at the sliding time is concentrated on the top of the projection 4, design features are not considerably damaged. If a projecting part of the projection is formed with a large curvature, the projection becomes hard to distinguish by eyes, which is favorable from the design viewpoint.
