Hereinafter, the structure of this invention will be explained with reference to embodiments shown in FIGS. 1 and 2 of the accompanying drawings. First, in FIG. 1, reference numeral 11 indicates a CRT, and a metal band 12 having an X-ray shielding function is wrapped around the front edge of the CRT 11. The CRT 11 is housed in a frame 20 which will be described later, and the CRT 11 is fixed in the frame 20 by fastening a wedge 13 made of an elastic material to a presser plate 14 with screws 15. In the frame 20, a side plate 21 is formed to follow the peripheral shape of the CRT 11, and the end of this side plate 21 becomes a step 22 on which the front surface of the CRT 11 is placed. The flange 23 forms a curved surface that is concentric with the curved surface containing the flange. Then, the side plate 21 of the frame 20, the flange 2
Screw seats 21a and 23a are formed at several places on the outer periphery of 3, so that the screw 15 and a screw to be described later can be respectively screwed into the screw seats 21a and 23a. Furthermore, the stepped portion 22 of the CRT 11 and the frame 20
An annular ring 16 is accommodated in a clamped state on the contact surface with the frame 20, and a cooling fluid R injection port 24 is formed in the side plate 21 of the frame 20, and a diaphragm 25 is provided in the injection port 24 to close it. There is. An annular ring 26 is attached to the front end of the frame 20, in other words, to the end face of the flange 23, and the open face of the front end of the frame 20 is sealed with a lens 30 with the ring 26 sandwiched therebetween. This lens 30 has a flange 31 projecting from its periphery, and a screw seat 32 is formed in a part of this flange 31 and aligned with the screw seat 23a. A screw 34 is screwed into this screw seat 32 via a washer 33 to connect the lens 30 and the frame 2.
0 is integrated with the CRT 11 and the CRT 11 is fixed to the frame 20 by the above-mentioned means, so that a space S containing the cooling liquid R is formed between the front surface of the CRT 11 and the lens 30. Therefore, if the performance of the lens 30 or CRT 11 deteriorates over time and it becomes necessary to replace it, for example, when replacing the lens 30, the coolant R can be pumped into the filling port 2 by removing the diaphragm 25.
4, loosen and remove the screw 34, uncouple the lens 30 and frame 20, and replace it with a new lens 30. When replacing the CRT 11, remove the screw 15 and uncouple the frame 20 and CRT 11.
Apply a new CRT11 and reassemble by connecting with screws 15.

As is clear from the above description, in the projection television apparatus of this invention, the cathode ray tube, frame, and lens are each removably provided. Therefore, the cathode ray tube containing the coolant and the lens can be removed as a unit from the apparatus main body, and the cathode ray tube or lens can be easily replaced. In addition, since the coolant-filled space provided on the front end of the cathode ray tube is essentially made up of the minimum necessary parts of the cathode ray tube, frame, and lens, the structure of the device itself is simple and easy to assemble. This reduces the workload and leads to lower manufacturing costs. Furthermore, when the cathode ray tube is fixed in the frame by means of a wedge made of elastic material, the positional relationship between the two is accurate and constant.
