| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a magnetic shield capable of preventing production of burrs due to external vibration when stacked. SOLUTION: This magnetic shield 1 is used by being mounted to a cathode- ray tube, and generally spherical surface-like projections 8a, 9a each projecting in opposite directions to each other are formed on corner shielding parts 8 and receiving parts 9 which become facing parts in its stacked state. When it is actually stacked with the other one, the contact area and contact resistance between the magnetic shields are small as compared with a conventional one, so that the production of burrs due to external vibration can effectively be prevented. |
