ABSTRACT:
A connecting rod comprises a rod body having a small end and a base end provided with a threaded hole, and a cap provided with a through hole corresponding to the threaded hole to be joined to the base end of the rod body with screws to form a large end. The joining surface of the base end to which the joining surface of the cap is to be joined is inclined to a plane perpendicular to the longitudinal axis of the rod body. The threaded hole of the base end is formed by tapping a preformed hole by means of advancing a drill from the joining surface of the base end obliquely toward the longitudinal axis of the rod body. The preformed hole has a bottom in a wall forming the rod body, and a chip removing hole is formed in a side surface of the wall of the rod body so as to be connected to the bottom of the preformed hole for the threaded hole.
