PROBLEM TO BE SOLVED: To improve the stiffness of the box body of a unit body by extending a bead on the top board of the box body of a unit body that is composed by accommodating a heat exchanger and a fan. SOLUTION: A unit body 35 is composed by accommodating an indoor heat exchanger, a fan, and a fan motor in a box body 54. On a top board 39 of a box body 54 in the unit body 35, a plurality of, for example two, beads 60 and 61 projecting toward the inside of the box body 54 are formed by pressing bend machining. The beads 60 and 61 are extended linearly from one end edge 39C to the other end edge 39C that oppose each other in the top board 39 and are provided in parallel. The formation of the beads 60 and 61 increases the strength of the top board 39 and improves the stiffness of the box body 54. In this case, the one end edge 39C of the top board 39 is in contact with a side plate 38C, and the other end edge 39D is in contact with a side plate 38D being installed opposite to the side plate 38C. |
