A CRT coupling apparatus of a projection television couples a CRT which forms a picture to a lens which magnifies the picture formed by the CRT and projects it onto a screen. The CRT coupling apparatus includes: a CRT bracket supporting the CRT; a lens bracket supporting the lens; a coupler placed between the CRT and the lens; and a spring wire fixing the CRT bracket and the lens bracket to the coupler by applying elastic force in mutually approaching directions. One side of the spring wire is connected to a side of the CRT bracket facing away from the coupler, and the other side of the spring wire is connected to a side of the lens bracket facing away from the coupler. The apparatus also includes an earth assembly installed in the CRT bracket and contacting a backplate of the CRT to draw static electricity generated in the CRT away from the CRT. Sealing elements are provided between the coupler and the CRT and lens, respectively.
