Claims

[Claims for Utility Model Registration] A coil including a generally long cylindrical coil bobbin made of a relatively hard material and a self-tapping threaded core screwed into the inner cavity of the bobbin, the coil bobbin comprising: at least three rigid axial ribs projecting inwardly at generally equal intervals circumferentially to receive the core; and between the axial ribs, at least on the outer circumference of the threaded core; a flexible axial rib protruding from the inner circumferential surface of the coil bobbin; and an elastic material layer covering at least an inner tip of the axial rib. .
