It includes a sheet material ST that can be deformed into a second form to be secured. In the first form, the sheet material ST has a first bent portion 68, and in the second form, the sheet material ST has a shape in which the first bent portion 68 is stretched flat. In this way, by stretching the first bent portion 68 of the sheet material ST in the first form flatly in the second form, it is possible to use the sheet material ST in the second form rather than using the sheet material ST in the first form as it is. Wide maintenance spaces MS1 and MS2 can be efficiently secured using the sheet material ST.

(2) In the embodiment described above, the sheet material ST has the second bent portion 69 in both the first form and the second form. In the second form, the sheet material ST includes a first portion 71 disposed on one side with the second folded portion 69 in between, and a second portion 72 disposed on the other side. The first portion 71 is arranged along the side surface (left side plate 43 or rear side plate 42) of the air conditioner 10, and the second portion 72 secures maintenance spaces MS1 and MS2. Thereby, the first and second portions 71 and 72 of the sheet material ST divided by the second folded portion 69 can be appropriately utilized to secure the maintenance spaces MS1 and MS2. In particular, by arranging the first portion 71 along the side surface of the air conditioner 10, the attachment area of the sheet material ST to the air conditioner 10 can be expanded, and the sheet material in the direction perpendicular to the side surface (left-right direction X or front-back direction Y) can be expanded. The material ST can be positioned.

(3) In the above embodiment, in the second form, the sheet material ST has first to sixth cut and raised parts 81 to 86 that are partially cut and raised from the state of the first form. The sheet material ST has first and second cut-and-raised portions 81 and 82, which have openings A1 and A2 through which parts that protrude from the air conditioner 10, such as the electrical component box 54, the drain pipe 26, and the liquid side piping connection port 28, are inserted. formed by. Among these, the sheet material ST is positioned at a predetermined position by the protruding portion (drain pipe) 26 inserted into the opening A1 formed by the first cut and raised portion 81. Thereby, the sheet material ST of the second form can be positioned at a predetermined position using the first cut and raised portion 81.

(4) In the embodiment described above, the fifth and sixth cut-and-raised portions 85 and 86 are inserted into the recess formed in the air conditioner 10, for example, the suction port 42a formed in the casing 40. The sheet material ST is positioned at a predetermined position by bringing the fifth and sixth cut-and-raised portions 85 and 86 into contact with the periphery of the recessed portion 42a. Thereby, the sheet material ST of the second form can be positioned at a predetermined position using the fifth and sixth cut-and-raised portions 85 and 86. The fifth and sixth cut-and-raised portions 85 and 86 may be inserted into a recess other than the suction port 42a. One of the fifth and sixth cut-and-raised portions 85 and 86 may be omitted and only the other may be used for positioning the sheet material ST.

(5) In the embodiment described above, the third and fourth cut-and-raised portions 83 and 84 are arranged to intersect with the first bent portion 68. In the second form, if the first bent portion 68 of the sheet material ST is made into an elongated shape, there is a possibility that the sheet material ST will naturally bend at the first bent portion 68 due to the habit of the sheet material ST or the influence of gravity. be. By forming the third and fourth cut-and-raised portions 83 and 84 to intersect with the first bent portion 68 as described above, a rib for maintaining the first bent portion 68 in an extended state is formed. Third and fourth cut-and-raise portions 83 and 84 can be used. Note that the third and fourth cut-and-raised portions 83 and 84 only need to intersect with the first bent portion 68, and do not necessarily need to intersect at right angles. One of the third and fourth cut-and-raised portions 83 and 84 may be omitted, and only the other may function as a rib.

(6) In the above embodiment, the sheet material ST is made of a corrugated cardboard sheet, and the second folded portion 69 is along the line STa of the corrugated cardboard sheet. Therefore, in the second embodiment, the state in which the sheet material ST is bent at the second bending portion 69 is easily maintained.

(7) In the above embodiment, the maintenance spaces MS1 and MS2 are secured around the air conditioner 10 by the following method. The method includes a step of removing the packing materials 61 and 62 packing the air conditioner 10 from the air conditioner 10, a step of deforming at least one bent portion 68 of the packing materials 61 and 62 into a flat shape, and a step of The method includes a step of securing maintenance spaces MS1 and MS2 by attaching the materials 61 and 62 to the air conditioner 10 installed at predetermined locations. In this way, by stretching the bent portion 68 of the sheet material ST in the first form flatly in the second form, the sheet material ST in the second form can be used more easily than in the first form as it is. Using this, it is possible to efficiently secure large maintenance spaces MS1 and MS2.
