PROBLEM TO BE SOLVED: To promote the removal and release of chips produced on the mating fractured surfaces by abutting the fractured surface of a cap part and the fractured surface of a rod part immediately after being fractured and divided into the cap part and the rod part. SOLUTION: A device for manufacturing a connecting rod comprises a fixed stage 62 secured onto a base 60, a movable stage 64 so installed as to be move close to or apart from the fixed stage 62, and a set of backup cylinders 153, 155 displacing the overall movable stage 64 along the axial direction of the connecting rod 30. The set of backup cylinders 153, 155 are substantially simultaneously biased to displace a cap part 32 together with the movable stage 64 until the fractured surface of the cap part 32 of the connecting rod abuts on the fractured surface of the rod part 34 of the connecting rod held on the fixed stage 62.
