         9 . The outdoor unit of  claim 6 , wherein fastening holes provided in the lower-pressure service valve are aligned by fastening holes provided near an end of the first fitting portion and fastened by a fastener. 
     
     
         10 . The outdoor unit of  claim 1 , wherein a plurality of fastening holes provided in a left portion of the upper plate and a plurality of fastening holes provided in a right portion of the lower plate are aligned by a plurality of fastening holes provided in the housing and configured to be fastened by a fastener. 
     
     
         11 . The outdoor unit of  claim 1 , wherein a fastening hole provided in the right portion of the upper plate is aligned by a fastening hole provided in the left portion of the lower plate, at a lower end, and configured to be fastened by a fastener. 
     
     
         12 . The outdoor unit of  claim 1 , wherein a fastener configured to fasten pipes is provided at an upper end portion of the first service valve to face in a right direction where the lower plate is to be fastened. 
     
     
         13 . The outdoor unit of  claim 1 , wherein a fastener configured to fasten pipes is provided at an upper end portion of the second service valve to face in a left direction where the upper plate is to be fastened. 
     
     
         14 . The outdoor unit of  claim 1 , wherein a fastener configured to fasten pipes is provided at an upper end portion of the first service valve to face in a left direction opposite to a direction in which the lower plate is fastened. 
     
     
         15 . The outdoor unit of  claim 1 , wherein a fastener configured to fasten pipes is provided at an upper end portion of the second service valve to face in a right direction opposite to a direction in which the upper plate is fastened.
