Claims

[Claims for Utility Model Registration] 1. A tube body consisting of a funnel having a neck and a panel having a screen formed on the inner bottom surface of the funnel; An electron gun that emits an electron beam built in the neck; A shadow mask disposed in the inner space of the panel so as to be close to each other; An inner shield for magnetic shielding located in the inner space of the funnel; A frame fixed to the panel in a state in which the shadow mask and the inner shield are attached. a substantially wedge-shaped head that penetrates through holes formed in the inner shield and the frame and engages with the bottom surface of the edge of the frame; and a head that is in contact with the top surface of the edge of the through hole of the inner shield; a contact spring made of a plate material having a substantially C-shaped contact portion extending from the one leg and contacting an internal conductive film of the funnel; . 2. The cathode ray according to claim 1, wherein the contact portion is partially formed flat so as to correspond to the inner surface of the funnel, thereby increasing the contact area of the contact portion with the conductive film on the inner surface of the funnel. tube.
