In the large end of the connecting rod, which has an oil inlet that communicates with the oil supply hole that supplies oil to the small end and supplies oil from the metal bearing to the oil supply hole, the lower end of the oil supply hole is blinded by the oil inlet that opens into the top metal of the metal bearing. The oil inlet is closed by a stopper, and the oil inlet is formed to diagonally pass through the big end body from the oil supply hole and open at the end of the big end body in the axial direction of the crank pin. The large end of the cooking stove is characterized by:
