Claims

[Scope of utility model registration request]

A bolt insertion hole is provided that passes vertically through the upper half of the body side and the lower half cap that form the large end of the connecting rod, and exposes the vicinity of the mating surface to the bearing mounting surface side. The = side or opposite side of the shaft part is a notched flat surface along the axial direction, and bolts are provided for tightening, and bearing split bodies are fitted to the upper and lower half caps on the main body side, respectively, The large end of the connecting rod is tightened by inserting a bolt into the bolt insertion hole, bringing the notch-shaped flat surface near the mating surface into contact with the outer peripheral surface of the bearing, and screwing and tightening a nut.
