摘要： An object of this invention is to provide a connecting rod in which a pair of ball-shanks are connected to a rod main body such that they are axially perpendicular to each other, having a sufficient strength and which can be produced easily and at low cost, and a manufacturing method thereof. The connecting rod of this invention to achieve such an object comprises first and second ball-shanks and a rod main body to which the first and second ball-shanks are connected freely swingably and rotatably. The first ball-shank is connected to the rod main body such that the shank portion is perpendicular thereto, while the second ball-shank is connected to the rod main body such that the shank is in parallel thereto. Further, the rod main body is die cast with a ball portion of each ball-shank inserted as a core.
