ABSTRACT:
A compressor capable of surely preventing leakage of a refrigerant gas from a connection portion between an airtight container and a pipe to the outside at low cost is provided. The compressor comprises an airtight container to which a refrigerant introduction pipe is connected, and a compression element received in the airtight container to discharge the refrigerant into the same. The refrigerant introduction pipe has a cylindrical pipe main body, and a jaw-like flange portion formed in a tip of the pipe main body. A cylindrical connection sleeve is disposed between the refrigerant introduction pipe and the airtight container. A first bolt is disposed to connect the connection sleeve to the airtight container, and a second bolt is disposed to connect the connection sleeve to the flange portion of the refrigerant introduction pipe. The flange portion of the refrigerant introduction pipe hides the first bolt.
