ABSTRACT:
An internal combustion engine is provided with a bore for receiving the journal of a crankshaft which bore is defined by a lower section of a cylinder block and a bearing cap secured to the cylinder block. A cylindrical housing provided at its inner surface with a metal sleeve bearing is disposed in the bore so as to rotatably support the crankshaft journal. Additionally, a cylindrical elastic member is securely disposed between the outer surface of the cylindrical housing and the peripheral surface of the bore, thereby absorbing vibration transmitted through a piston to the crankshaft, which vibration is due to pressure generated in engine cylinders.
