A hermetic compressor is provided to effectively remove foreign materials generated due to friction, between an eccentric shaft part and a connecting rod of a crank shaft, by using an oil guiding groove. A hermetic compressor comprises a connecting rod having a first end part(62), a second end part and a connection part. The first end part has a first though hole(61) in which an eccentric shaft part is pivotally connected, and combines with an eccentric shaft part. The second end part has a second through hole in which a piston pin jointing to a piston is pivotally connected, and combines the piston. The connection part connects the first end part and the second end part, and has a through hole(65) communicating the first through hole and the second through hole in order to supply the oil. An oil guidance groove(61a) for ejecting foreign materials is formed on an inner wall of the first through hole.
