The invention provides a compressor which has a sleeve (141), and the sleeve (141) is arranged correspondingly to a through hole (102) of a bending surface (100) which forms a sealed container (12), and is connected with a refrigerant pipe. The sleeve (141) has a small outer diameter part (152), a big outer diameter part (153) and a diameter shrinking part (154) which are arranged in a continuous way through an annular step part (151), the diameter shrinking part (154) takes a capitellate shape at the opening end side of the small outer diameter part (152), a communicating pore (155) which runs through the small outer diameter part (152)and the big outer diameter part (153) has a small inner diameter part (155A) and a big inner diameter part (155C), the small inner diameter part (155A) is mainly arranged at the small outer diameter part (152), the big inner diameter part (155C) is connected with the small inner diameter part (155A) through an annular step part (155B), and is arranged at the big outer diameter part (153), a diameter expanding part (155a), the inner diameter of which gradually increases towards the opening end side, is arranged at the opening end side of the small inner diameter part (155A), and a tube component (145) made of copper is embedded into the big outer diameter part (155C) to be carried out with solder brazing under the state that one end is contacted with the step part (155B), so as to be fixed in the sleeve (141); thus, the compressor which can enable the sleeve arranged in the sealed container through projection welding to be miniature is provided, and the refrigerant pipe and the sleeve are simply connected with a right angle, thereby the sealed container cannot suffer the seat thrust greatly when the sleeve is arranged in the sealed container by welding.
