To provide a connecting rod device of a hermetically sealed reciprocal compressor simple in structure and improved to reduce abrasion and noise.

The connecting rod device of the hermetically sealed reciprocal compressor is a connecting device of the hermetically sealed reciprocal compressor to convert a rotary movement into a reciprocal sliding movement by connecting an eccentric part of a crankshaft and a piston to each other and includes a ball, a first connecting member having a small diameter part connected with a piston pin being connected with the piston and a connecting part extended from the small diameter part, which has a ball embracing surface to embrace the ball and support the ball to be moved, a second connecting member having a large diameter part rotatably connected with the eccentric part and an extending yoke part in a specified shape at an outside of the large diameter part, which supports the ball against the embracing surface and prevents the ball from being separated and a fastening member to fasten the connecting part of the first connecting member and the second connecting member such that the first connecting member and the second connecting member relatively move with the ball being placed between them.
