In a connecting apparatus of a hermetic reciprocal compressor to convert a rotary movement into a reciprocal sliding movement by connecting an eccentric portion of a crankshaft and a piston, the connecting apparatus has a ball; a first connecting member having a small diameter portion connected with a piston pin being connected with the piston, and a connection portion extended from the small diameter portion, which has a ball embracing surface to embrace the ball and supports the ball to be moved; a second connecting member having a large diameter portion rotatably connected with the eccentric portion, and an extending yoke portion at an outside of the large diameter, which supports the ball against the embracing surface and prevents the ball from being separated; and a third connecting member to connect the first connecting member and the second connecting member such that the first connecting member an the second connecting member relatively move with the ball being placed therebetween. |
