PURPOSE: To reduce component cost and assembly work cost with a mount structure simplified by integrally molding screwing bosses to a board holder and by making screw fixture in the form of sandwiching a chassis by these board holder screwing bosses and a cabinet.

CONSTITUTION: A cabinet mount structure of this CRT display is constituted of a chassis 1 serving as the base to mount packaging components, a board holder 2 to fix a circuit board, a cabinet 3, and screws 4. The board holder 2 is in the way of assembly fitted to temporarily set on the chassis 1 by a claw 2b integrally molded to the board holder 2. Finally, the chassis 1, board holder 2, and cabinet 3 are fixed firmly at the same time by clamping the screws 4 to screw boss 2a. The work for fixing the board holder 2 is simple by only hooking the claw 2b on the chassis 1 and requires no screws or no separate stoppers.
