Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a crankcase structure of an internal combustion engine, suppressing an increase in weight by restricting the thickness of the cylindrical peripheral wall of a crankcase and ensuring necessary rigidity and strength. SOLUTION: In this crankcase structure of the internal combustion engine, the cylindrical peripheral wall 31c extends outward in a crankshaft direction from the sidewall 31Rw of the crankcase, the opening of the cylindrical peripheral wall 31c is covered with a case cover 77, and an engine hanger 18 formed on the cylindrical peripheral wall 31c is coupled to and supported by a vehicle body frame. A case reinforcing member 78 formed annularly along the opening end surface of the cylindrical peripheral wall 31c and formed thickly in a radial direction is fixed to the opening end surface of the cylindrical peripheral wall 31c to partially overlap with the engine hanger 18.
