PURPOSE:To obtain a picture tube device which improves the fixation precision of a deflecting yoke without reference to an error in manufacture, by fitting an adjustment window frame to the picture tube body itself or a picture tube. CONSTITUTION:A filter 5 is fitted to the front surface of the panel part of the picture tube 1 through resin 8. This filter 5 is stuck by the resin 8. After band reinforcement is performed by wrapping a fitting lug 9, the deflecting yoke is fixed. Then, the window frame 6B is rotated and adjusted in a circumferential direction of a tube axis is conformity to a fluorescent screen 2 or a raster and then fixed to the device body with a thumb screw 4. Therefore, even when the window frame 6B is rotated anf fixed to the fluorescent screen 2, the window frame 6B is adjusted and fixed directly, so there is no adjustment error such as an error in manufacturing the screen 2 and an erro in fixing the fitting lug 9 and picture tube 1. |
