Abstract: The present invention relates to an extrusion-type connecting rod which is installed between a piston and a crank and can convert the reciprocating motion of the piston into the rotary motion of a crank shaft, an extrusion apparatus for a connecting rod, and a manufacturing method for the extrusion-type connecting rod. The extrusion-type connecting rod may comprise: a first big end having a portion of a crank shaft hole formed on one side and having a seam-line divided surface, which comprises a seam line formed at the time of extrusion, formed on the other side; a second big end, being extrusion-molded simultaneously with the first big end, having the other portion of the crank shaft hole formed on one side, and having a seam-line divided surface, which comprises a seam line formed at the time of extrusion, formed so as to contact the seam-line divided surface of the first big end; a connection part which is extrusion-molded integrally with the second big end; and a small end which is extrusion-molded integrally with the connection part.
