Abstract
A tension band for fastening a cathode ray tube and a cathode ray tube fastened with the band around the skirt of the panel thereof are disclosed. The band comprises a single band unit having no seam therein and is made of synthetic resin mainly containing polyamide and glass fiber. The content ratio of the polyamide to glass fiber is preferably 3:7 to 7:3. Before the band is mounted on the cathode ray tube, the ratio of the inner circumference of the tension band as against the outer circumference of the skirt of the panel is preferably 98.79-99.90%. The tension band is easy to manufacture and place on the cathode ray tube, effectively preventing crack expansion and implosion of the cathode ray tube.
