Connecting rod apparatus of hermetic compressor

A connecting rod apparatus for converting a rotation to a reciprocal linear motion by connecting an eccentric portion of a crank shaft to a piston, comprising:

• a bushing having a cylindrical body having first and second opposite ends and an inner bore defining a central axis, the cylindrical body having a sloping side at an outer surface sloping from the first end to the second end with the body defining an outer circumference that is eccentric from the central axis, and being rotatably connected to the eccentric portion of the crank shaft, the sloping side having a predetermined slope;
• a connecting rod having a piston attachment formed at one end of the connecting rod for being connected with a piston pin connected with the piston, and a connecting portion formed at another end of the connecting rod for being connected with the bushing;
• and
• a connecting member connecting the connecting portion of the connecting rod and the bushing so that the connecting portion and the bushing can move relative to one another.
