Claims

[Scope of utility model registration request]

A main bearing cap member having the other bearing surface of the main bearing surfaces that pivotally supports the crankshaft is joined to the skirt portion of the cylinder body having one of the main bearing surfaces that pivotally supports the crankshaft, with the crankshaft in between. The vibration damping structure of the cylinder body has reinforcing ribs formed along the skirt at the joint.
