A V-type engine includes: first and second banks which are arranged in a V-shape and which respectively have cylinder bores; a crankshaft which is shared by the first and second banks; a crankcase which supports the crankshaft, the first and second banks being connected to the crankcase; and a valley portion which is defined between the first and second banks, an engine auxiliary machine being disposed in the valley portion. The first and second banks are arranged so that a cylinder center line of the first bank and a cylinder center line of the second bank respectively pass through a point which is eccentric from a rotational center of the crankshaft to a side opposite from both the banks. Thus, it is possible to improve an auxiliary machine housing function of the valley portion defined between the first and second banks while maintaining a predetermined opening angle therebetween.
