PROBLEM TO BE SOLVED: To install piping without moving an installing position by providing a hole for piping so as to distend to form it at a plurality of stages from a rear end of an indoor unit side face toward forward, and forming the hole so as to further widely distend it from a width for passing a refrigerant piping and drain hose to further wider. SOLUTION: A piping hole forming part 10 for forming a hole for piping is provided at a lower part of a side 1b of an indoor unit 1. Upper and lower notched holes 11 are formed at the part 10. The holes 11 are formed by providing a normally notched hole 11a perforated at a position for forming the hole for piping and a distended notched hole 11b perforated at a position for widely distending the hole for piping. Separating grooves 12 are formed by recessing a side of the unit 1. A normally separating cut groove 12a arriving at a rear end of the unit 1 from a rear end of the hole 11a to communicate the upper and lower ends of the holes 11a with one another and a distending separating cut groove 12b arriving at the hole 11a from the rear end of the hole 11b to communicate upper and lower ends of the hole 11b are provided. |
