関。 A pump casing of a centrifugal water pump is disposed on the outer surface of a flywheel fixed to an end of a crankshaft and has a spiral water passage formed around the outer periphery of an impeller accommodation chamber, and the impeller accommodation chamber has a pump casing. In an internal combustion engine equipped with a centrifugal water pump, in which an impeller built in the pump casing is connected to an end of the crankshaft on the flywheel mounting side, the entire spiral chamber surrounding the spiral water passage and the flywheel are attached to the pump casing. The lid of the flywheel housing that surrounds the wheel is formed integrally with the lid of the flywheel housing by casting, and at least a slight gap is formed between the inner peripheral surface of the impeller housing chamber in which the spiral passage opens and the outer peripheral surface of the impeller. An internal combustion engine equipped with a centrifugal water pump, characterized in that the impeller housing chamber has cylindrical machined surfaces facing each other, and a pump lid with a water inlet is fitted to the outer extension opening end of the impeller housing chamber. .
