In a closed compressor provided with a ball joint, there was needed a structure easy to assemble and capable of sufficiently supplying the lubricating oil to a ball joint section in order to ensure smooth sliding between a ball and a ball seat. The closed compressor is provided with a ball joint section. In the ball joint section, flat cut portions are formed in the outside diameter of the ball of the connecting rod, parallel with the end face of a ring. Also a groove is formed for insertion of the ball into the ball seat from the end of the crankshaft side which is an open end of the piston. The groove has the same width as the width between the flat cut portions of the ball. <IMAGE>
