An axis flow path is formed inside of a crankshaft. The axis flow path has an end surface opening at an end surface at one end of the crankshaft. An oil gallery is formed inside of a crankcase and has a first attachment hole in a right sidewall portion of the crankcase. A cover member is provided at part of the right sidewall portion of the crankcase. An oil path and a second attachment hole connected to the oil path is formed in the cover member to communicate with the axis flow path of the crankshaft. The first and second attachment holes are directed in different directions from each other. The first attachment hole and the second attachment hole are connected to each other by first and second metal pipes.
