To solve such problems that mounting of thin TV sets recently rapidly increasing on furniture poses an overturning problem for comparatively small models mounted on stands because of their high centers of gravity and makes it difficult to unerringly fix heavy thin TV sets to wall surfaces with the TV sets put on TV boards and poses a safety problem when a child touches the TV set as well when an earthquake occurs.

Safety is secured by simply and unerringly holding a thin TV set on furniture for installing the thin TV set by erecting supports 2 and 2 in the back of a furniture body 1, mounting the board 3 between the supports 2 and 2 and fixing the back of the thin TV set 4 to be installed on the furniture body 1 to the board 3.
