  However, in the above-described conventional technology, in order to prevent overturning, a member such as a hook-like body, a band insertion hole, or a flange shape must be provided in advance on the back and bottom of the AV equipment mounted on the rack. The rack had to be fitted with a fitting shape. For this reason, there is a problem that versatility is low, not preventing any AV device mounted on the rack from falling.

  In recent years, TVs equipped with an electric or manual swing mechanism that can rotate the TV main body to the right and left by remote control to position the TV screen in a desired direction have been put on the market. In the fall prevention device that provides a band insertion hole and fixes the TV to the fixed body via a string or band, the distance between the TV and the fixed body is fixed (that is, not changed). There is also a problem that the swing mechanism cannot be operated.

  Therefore, the main object of the present invention is to provide a structure for preventing overturning of AV equipment and the structure that can be applied to all types of racks and AV equipment regardless of the type of rack and the type of AV equipment to be mounted. It is to provide a rack for adopted AV equipment.
