Rotary compressor

A rotary compressor comprising:

• a casing;
• a compression mechanism housed in the casing, the compression mechanism having a suction port;
• a joint pipe fixed to the casing, the joint pipe being formed into a cylindrical shape;
• a suction pipe arranged inside the joint pipe, the suction pipe communicating with the suction port of the compression mechanism;
• and
• an accumulator including an outlet pipe connected to an inlet end of the suction pipe,
• the suction pipe having
• a large diameter portion formed on an inlet side of the suction pipe, the large diameter portion being fixed to an inner peripheral surface of the joint pipe, and
• a small diameter portion formed on an outlet side of the suction pipe, the small diameter portion having a smaller outside diameter than the large diameter portion,
• the joint pipe being made of an iron-based material,
• a clearance being formed between an outer peripheral surface of the small diameter portion of the suction pipe and the inner peripheral surface of the joint pipe.
