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