Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a low costs and high performance lens unit device for a projection television capable of improving a productivity through reducing the number of parts and enhancing work efficiency. SOLUTION: The lens unit device has a structure molding a twin lens 3, a spacer 2 of R, G and B unit consisting of CRT 4 in one piece and also directly to a cabinet. An injecting hole 2a and a tank 10 to cool the CRT 4 is mounted at two places of each midpoint of the unit. The hole 2a has a structure being blocked only by insertion using a push liquid 12 and a packing liquid 13. The lends 3 and the CRT 4 are assembled after mounting of gaskets 7, 8 having O ring shaped protrusions 7a, 8a, respectively.
