Claims

[Scope of utility model registration request]

A long hole opening downward is formed in the rib of the shaft bearing inside the skirt portion of the cylinder block, and a through hole is provided through the long hole to look into the side wall recess around the hoar above, and the long hole has an offset step. The stepped part of the tension bar is fitted into the tension bar, which is made up of two shaft parts extending in opposite directions, and one shaft of the tension bar is inserted through the through hole and the cylinder head to extend upward. The other shaft of the tension bar extends downward through a shaft bearing rib integrally provided in the undercrankcase, which is an oil pan part, and is connected to the cylinder by a nut screwed onto each shaft end. An engine body joint structure characterized by a head, cylinder block, and undercrankcase that are integrally joined.
