PROBLEM TO BE SOLVED: To allow products having different mounting forms to be surely discriminated from one another. SOLUTION: A plurality of engraved marks 24a, 24b (identifiers) corresponding to a plurality of mounting forms of a lever 20 (mounted member) to a housing 10 are engraved on the housing 10 (base member); and the housing 10 is provided with a selective display means (covering parts 16F and 16R and a window hole 17) for exposing, in the state where the lever 20 is mounted, only the engraved marks 24a, 24b corresponding to its mounting form and for covering the engraved marks 24a, 24b corresponding to the other mounting forms. Since only the corresponding engraved marks 24a, 24b are displayed in accordance with the mounting form, a product is easily and surely discriminated. COPYRIGHT: (C)2007,JPO&INPIT
