A horizontal connecting member that connects the pair of left and right vertical connecting members to each other in a horizontal direction, wherein at least one of the vertical connecting member and the horizontal connecting member is extendable and contractible.

In the mounting plate according to the first aspect of the present invention, when the vertical connecting member is expandable and contractible, the vertical connecting member of the mounting plate is adjusted so that the mounting size of the indoor unit and the vertical engaging portion of the mounting plate match. It is stretched or shortened and its length is adjusted in the longitudinal direction. When the horizontal connecting member is expandable and contractible, the horizontal connecting member of the mounting plate is expanded and contracted, and the horizontal length of the mounting plate is adjusted as in the case of the vertical connecting member. When both the vertical connecting member and the horizontal connecting member can expand and contract, the vertical and horizontal connecting members of the mounting plate are expanded and contracted, and the length of the mounting plate in both the vertical and horizontal directions is adjusted. The installation plate whose length has been adjusted is mounted on the wall, and the indoor unit is mounted on the wall by being engaged with the upper and lower engaging portions of the installation plate.

The mounting plate in which only the vertical association member (or the horizontal association member) can be expanded and contracted is commonly used for indoor units having only different vertical (or horizontal) mounting sizes. on the other hand,
When both the vertical connecting member and the horizontal connecting member can expand and contract, they are commonly used for all types of indoor units.

The indoor unit installation plate according to the second aspect of the present invention is characterized in that the upper engaging portion and the lower engaging portion are provided with mounting holes respectively.

The mounting plate according to the second aspect of the present invention is fixed to the wall by inserting screws into the mounting holes of the upper and lower engaging portions. In this case, a portion for supporting the weight of the indoor unit when the indoor unit is mounted on the installation plate and a mounting portion for fixing the installation plate to the wall exist in the same upper / lower engagement portion. Therefore, since the distance between the supporting portion and the mounting portion is short, the weight of the indoor unit is firmly supported, and the installation plate is hardly bent or the screws are hardly dropped.

According to a third aspect of the present invention, in the indoor unit installation plate, at least one of the vertical connecting member and the horizontal connecting member is provided with a means for fixing an expanded or contracted state.
