Furthermore, by confirming that the fragments are collected in the collection bag 64, it is possible to confirm reliably and easily that the fragments have been removed from the rod body 7 and the cap portion 8. As described above, since the collection bag 64 has a transparent physical strength, the pieces collected in the collection bag 64 can be easily confirmed visually.
- the connecting rod 1 to which vibration is applied in this way is then transferred to a brushing device (not shown).
- a brushing device In this brushing device, the broken surfaces of the rod body 7 and the cap portion 8 are brushed. As a result, the fragments can be more reliably removed from both fractured surfaces.
- the connecting rod 1 from which the pieces have been removed in this manner is returned to the production line 10 and conveyed to the next station, and the rod body 7 and the cap portion 8 are connected via bolts. At this time, since the piece does not squeeze between the rod body 7 and the cap portion 8, relative displacement between the rod body 7 and the cap portion 8 is suppressed, and the connection accuracy is improved.
- the connecting rod 1 is finally assembled into the internal combustion engine. Even in this case, since the fragments are not squeezed between the connecting rod 1 and the crankshaft, it is possible to avoid a decrease in assembly accuracy. Further, since the fragments are not mixed into the engine oil, it is possible to prevent the engine oil from prematurely deteriorating.

- the rod main body 7 and the cap portion 8 may be temporarily connected to the connecting rod 1 before flowing into the production line 10.
- the contact plate member 30 may be removed to constitute the fragment removal device 20 so that the fragment is dropped only by the vibration of the air vibrator 26.
- a base 90 having a thickness larger than that of the base 24 may be inserted and the large end 6 may be placed on the base 90.
- the upper end surface of the base 90 and the bottom surface of the recess 52 of the anti-vibration base 48 should be flush with each other! ,.
- a gantry 92 on which a vibration-proof material pedestal 48 is installed and a gantry 94 on which the pedestal 50 is installed may be provided.
