Zusammenfassung:To protect reel 14 mounted on hub 12 in case 10, from shock, two annular shock shields 20 surround the hub and comprise compressible V- or U-shaped rings 40. Each shield can rotate with reel 14, has friction tips 44 to reduce friction, is located by its centre ring 26, and compresses axially and radially. Each shield may be relieved to form spokes (Fig. 1), and alternatively (Fig. 6) instead of rings may have conical deformations extending axially of the circular shield. Shield tab 30 engages the reel. The shields may be moulded from defined plastics.
