And a guide piece 6b. The guide piece 6b includes an upper piece 6b1, a lower piece 6b2, a left piece 6b3, and a right piece 6b4 toward the insertion port 6a. The upper piece 6b1, the lower piece 6b2, the left piece 6b3, and the right piece 6b4 support each other to assemble the guide piece 6b.

  In the assembling process of the protection member 6, first, as shown in FIG. 3, the upper piece 6b1 and the lower piece 6b2, the insertion port 6a existing between the upper piece 6b1 and the lower piece 6b2, and the insertion port A base 6c having a left piece 6b3 and a right piece 6b4 existing in 6a is prepared. Cut portions K1 are provided in the lower portions at both ends of the upper piece 6b1 of the base 6c and the upper portions at both ends of the lower piece 6b2, respectively. The left piece 6b3 and the right piece 6b4 are each provided with two notches K2 facing each other.

  Next, as shown in FIG. 4, both ends of the upper piece 6b1 and both ends of the lower piece 6b2 are bent about 45 ° toward the front side in FIG. 4 by the length of the cut portion K1. Next, as shown in FIG. 5, the upper piece 6b1 and the lower piece 6b2 are bent about 20 ° toward the back side in FIG. Then, as shown in FIG. 6, it is bent about 110 degrees from the position of each folding line L in FIG. 5 to the near side in FIG.

  Finally, as shown in FIG. 7, the left piece 6b3 and the right piece 6b4 are bent to the front side in FIG. 7 by about 45 °, and both ends of the upper piece 6b1 and both ends of the lower piece 6b2 are left piece 6b3 and right piece 6b4. It fits into each notch part K2. Thus, the left piece 6b3 and the right piece 6b4 are combined with both ends of the upper piece 6b1 and both ends of the lower piece 6b2, and the guide piece 6b as shown in FIG. 2 is assembled, and the protective member 6 is assembled by the cardboard base 6c. It is done.

  Such a protection member 6 is attached to each opening 5a of the leg 5 of the outdoor unit 1 as shown in FIGS. In this attachment, the upper piece 6b1 and the lower piece 6b2 are inserted into the opening 5a in the state shown in FIG. 6 from the back side (inside of the apparatus) of the opening 5a of the leg 5, and then the left piece 6b3 and the right piece 6b4. 7 are folded so as to expand to the left and right as shown in FIG. 7, and are combined with both ends of the upper piece 6b1 and both ends of the lower piece 6b2. Thereby, the protection member 6 is assembled as shown in FIGS. 8 and 9 (see FIG. 2), and is simultaneously fixed to the opening 5a.

  When the outdoor unit 1 described above is transported by a forklift, forklift claws F are inserted into the openings 5a of the legs 5 of the outdoor unit 1 (see FIG. 9). At this time, since each protective member 6 is attached to each opening 5a, each opening 5a is protected from the forklift pawl F by the protective member 6, and the forklift pawl F is inserted into the insertion port 6a of the protective member 6. Inserted. At this time, even if the forklift pawl F is inserted in a state of being displaced with respect to the opening 5a, it is guided to the insertion port 6a by the guide piece 6b of the protection member 6, so that the end of the opening 5a is protected. In addition, the periphery of the opening 5a is also protected.

  In addition, since the guide piece 6b of the protective member 6 extends from the insertion port 6a in four directions and is fixed to the opening 5a, the guide member 6b is partially fixed to the opening 5a, such as a fixing claw of the protective cover. The structure is strong against the impact of handling the load, and further, the structure is difficult to come off from the attached opening 5a. Thereby, since breakage and detachment are suppressed by the impact of handling the load, the opening 5a can be continuously protected reliably.

  Further, since the guide piece 6b is assembled by supporting the upper piece 6b1, the lower piece 6b2, the left piece 6b3 and the right piece 6b4, the protective member 6 is opened independently without using a tape or a stapler. Since it becomes possible to fix to the part 5a, compared with the case where a tape, a stapler, etc. are used, cost can be reduced and generation | occurrence | production of an unnecessary garbage can be prevented further.

  In addition, since the protective member 6 is made of corrugated cardboard, it can be easily disposed of and can be recycled. Further, the cardboard material is inexpensive, and the cost can be reduced as compared with the case where a protective cover made of plastic or metal is used.

  As described above, according to the embodiment of the present invention, the protective member 6 that protects the opening 5a for transportation formed in the leg portion 5 of the outdoor unit 1 from the forklift pawl F can be assembled by the cardboard material. When the cardboard material is assembled and the protective member 6 is completed, the protective member 6 is simultaneously formed. It is fixed to the opening 5a. The fixing force at this time is a structure maintaining force when the protective member 6 is assembled, and it is more resistant to the impact of handling the load than a structure that partially catches the opening 5a such as a fixing claw of the protective cover. Further, it is difficult to come off from the attached opening 5a. As a result, the opening 5a is prevented from being broken and the protective member 6 is prevented from coming off due to the impact of handling the load, so that the leg 5 can be reliably prevented from being damaged by the forklift claw F.

  Further, the guide member 6b for guiding the forklift claw F is formed in the protective member 6 so as to extend from the insertion port 6a in all directions, so that the forklift claw F is inserted in a state shifted from the opening 5a. However, since it is guided to the insertion port 6a by the guide piece 6b, the periphery of the opening 5a can be protected in addition to the protection of the end of the opening 5a.

  Further, the guide piece 6b is composed of an upper piece 6b1, a lower piece 6b2, a left piece 6b3 and a right piece 6b4 toward the insertion port 6a, and the upper piece 6b1, the lower piece 6b2, the left piece 6b3 and the right piece 6b4 are supported together. By assembling, the protective member 6 can be autonomously fixed to the opening 5a without using a fixing member such as a tape or stapler needle, so compared to the case where a fixing member is used, Costs can be reduced, and generation of unnecessary garbage can be prevented.
